Thank you so much for this video! I am in college and with the whole virus thing its really hard for me to keep up with math and really understand the problems, but this really really helped!
Thank you so much my teacher didn’t teach us this and she gave us the assignment but I didn’t understand so I came across this video and I got a 100 in the assignment thank you so much
That will vary as x varies. If you chose the minimum or maximum values for x, you get an extremely flat triangle with an extremely small angle. In the middle you get more typical triangles. If you set a value for x, you can use trig to find the exact angles. My approach would be to drop an altitude to form two right triangles. We know the hypotenuse and the right angle, and we know that the long leg of one is the same as the short leg of the other, and we know the sum of the other legs. Should be easy from here. ;)
If you know all numerical sides of a triangle, you can use the trig formula to find any of the angles. c² = a² + b² - 2ab * cosC Solve for cosC to get the angle.
This is just to find out the range of values that x could be for this to be a triangle. So x can be any value between 7/3 and 9 for this problem. If you choose any value for x such as 20, then you would get the sides to be 21, 41 and 73. You cannot form a triangle with these lengths. So x=20 is not a solution. The length of 73 is too long.
Amazing explanation! Thank you. Sadly it didn't help me understand how to use this concept with the squeeze theorem to find limits of two-variable fuctions, but I learned something new.
Yes, that would be an isoscoles triangle. (You can also have a triangle with all 3 sides equal to each other, that would be an equilateral/equiangular triangle, but that would not work for the triangle in this problem). You can find the value where 2 sides are equal by setting 2 sides equal to each other. 2x+1=4x-7 2x=8 x=4 So if x=4, plug the value in and you get the 3 sides to be 9, 9 and 5. Try with another set of sides. x+1=4x-7 3x=8 x=8/3 So if x=8/3, plug in the value and you get the 3 sides to be 11/3, 11/3 and 19/3. It will not work for the other set of sides because 2x+1 is greater than x+1 so those sides won't be equal and x cannot be zero for this to be a triangle.

not me being here during my geometry final😍
OMG!OMG!OMG! THANK YOU!THIS HELPS ALOT TO ME!!
You’re welcome Reika!
I owe you my life good sir. The concept clicked in my mind when you did the overlapping number line example. Thank you very much.
just want you to know your work does not go unappreciated
Damn don’t be mean 😪

Glad to hear my video helped you Ayanna!
And I’m also subscribing to this channel
I like that you said great job at the end. Made me feel better about understanding. Thanks Mr. Mario!
You’re welcome David!
Thank you. I have a midterm tommorow.
Good luck on your midterm Lucas! Report back if you want and let us all know how you did!
Thank you. God bless you!
Hi Johnny
U are the best.
Omg thank you so much! You teach better than my math teacher at my school😭😭
You are so welcome!
super helpful once again thank you so much
Happy to help!
Thank youuuu!!!!
tomorrow has test!
You’re welcome! Good luck on your test! Report back if you want and let us all know how you did.
Thank you so much
thank you johnny suns this was extremely helpful
Who is Johnny suns
thank you so much
That was very helpful, thanks!
Glad you liked the video Ankur!
Thank you helped me get my grade up from an f
THANKS DAWG
Thank you sir 😭
Most welcome
Thank you sooo sooo much, this helped a lot for my algebra exam
Great work Mario. Keep it up.
But this isn't what im looking for but this is useful information thanks teach
Thank you for this 😊
You’re welcome em horizon!
My math teacher spent over an hour explaining this and I still didn’t get it. This man took four minutes. Thank you.
Lol 😂
Thank you so much my teacher didn’t teach us this and she gave us the assignment but I didn’t understand so I came across this video and I got a 100 in the assignment thank you so much

How can you find the ° for each angle?
That will vary as x varies. If you chose the minimum or maximum values for x, you get an extremely flat triangle with an extremely small angle. In the middle you get more typical triangles. If you set a value for x, you can use trig to find the exact angles. My approach would be to drop an altitude to form two right triangles.

c² = a² + b² - 2ab * cosC
Solve for cosC to get the angle.
This video is very helpful Thank you sir
Going to take my final tomorrow , see you on the other side Mario
Can’t I just find x then plug it in and see what each side is equal to therefore I could just see how much each is worth
This is just to find out the range of values that x could be for this to be a triangle.

This is only for four minutes and my knowlege is now greater than 1 hour of math....
Glad my video helped you so quickly Antonio!
This video helped more than sitting in class for a week
Glad my video helped you Dave!
oh lord, Mario is the man. I have a midterm tmrw and this is the only thing I was unsure of. thank u
You’re welcome Jacob! Glad my video helped you prepare for your midterm!

mario you absolute legend
I looked up my math answers I didn't know how to do, but wanted to know how to cause it annoyed me that I didn't. This helped make me understand :)
Thank you 💖
You are so welcome
If it was given triangle is obtuse then ???
Yes this method will work for an obtuse triangle as well Pankaj!
I love you
This makes me realize how much my maths teacher really is bad at her job
The sum of two sides of a triangle can be equal to the third side when ө = 180 degree. Can we use this case to solve the problem g
If one angle is 180 degrees then it will no longer be a triangle. The sum of any two sides has to be greater than the third side.
Can you have equal amounte
Yes, that would be an isoscoles triangle. (You can also have a triangle with all 3 sides equal to each other, that would be an equilateral/equiangular triangle, but that would not work for the triangle in this problem).
You can find the value where 2 sides are equal by setting 2 sides equal to each other.
2x+1=4x-7
2x=8
x=4
So if x=4, plug the value in and you get the 3 sides to be 9, 9 and 5.
Try with another set of sides.
x+1=4x-7
3x=8
x=8/3
So if x=8/3, plug in the value and you get the 3 sides to be 11/3, 11/3 and 19/3.
It will not work for the other set of sides because 2x+1 is greater than x+1 so those sides won't be equal and x cannot be zero for this to be a triangle.
I did the same thing but my xes is 0, - 10 and possitive 4. I don't know how does it works. Anyone can help? 🥺
1 word: quarantine
yo where the fuck is mario judah
someone get this dude a rag lol
I am so confused
im still so confused
What if there were only two inequalities in the triangle ?
i suggest that you talk slower but it's fine i kinda got lost in the middle of the discussion.
try altering the video speed
This ain’t the triangle inequality...
