Thank you for the video, well there is something I didn’t understand which is the (angles generated by transversals) thing. I didn’t take this lesson at school yet that’s why it’s hard for me to understand but I would appreciate it if you could please make a video about this.
The angle with the degree (3x+10) is supplementary to (x-30) because vertical angles are the same. Then you add it up and separate the variables and numbers. You'll get 4x = 200. Divide that by 4 and you get x = 50. :D
Since the angle relationship in the diagram is complementary we know that both those angles added up will equal to 90. Write the equation then solve for x, ones you’ve solved for x substitute

(3x+10)+(x-30) and since it's supplementary it's 180 degrees; combine like terms 4x-20=180 then add +20 to twenty and 180, and that will equal to 4x=200 and divide them by 4, it will equal to x=50 Sorry if I was late
@@Detective_depther Seems I'm a little late... the angle with the degree (3x+10) is supplementary to (x-30) because if two straight lines intersect, it causes the angles that are in front of each other to be the same. :)
anyone care to explain how he solved 5:20 ?? i don't really understand it no matter how many times i replay the video and i'm not an english speaker so i don't quite understand what he's saying. please please help 😭😭😭
At 5:20, we are given two expressions, for two angles that combine to form a right angle, that is a 90 degree angle. Thus we simply add the two angles, and add them up to 90 degrees. 3*x + x + 10 = 90 Gather like terms: 4*x + 10 = 90 Rearrange to make x the subject: x = 80/4 Solution: x = 20
i have a math test in 2 days and it covers 4 topics and i dont know 2 of them so im watching this to learn one of them which are angle relationships also the test is 4 grades so wish me luck
There's two angles with algebraic definitions. You ask yourself what's the relationship between them? Are they? Vertical angles (nope) Adjacent angles (nope) Alternate interior angles (nope) Alternate exterior angles (nope) Same side interior angles (nope) Corresponding angles (nope) Complementary angles (nope) Unfortunately, they don't apply to any of these. However, both are vertical angles to other angles. When we look into that approach we see the corresponding vertical angles (opposite angles of each) qualify as "Same side interior angles". Since vertical angles are equal to each other we can use the same expressions for our equation. Same side interior angles add up to 180 degrees. Therefore we simplify the following expression for the answer: 3x + 10 + x - 30 = 180
Sorry dave but....did I get you wrong? The last pproblem, I get 40 but it's show 50 so I'm very confuse... =4x + 10-30 ( =20 ) = 180 =4x + 20= 180 = 4x + 160 (60÷4)= 180 ( 60÷4=40) x=40 I GET THE ANSWER OF 40 BUT IT'S SHOW ON THE VIDEO THAT THE ANSWER IS 50...I DON'T KNOW WHY...
I'd recommend you post timestamps, when asking questions specific to a part of the video, since letters can mean all sorts of different things depending on the context. I assume you are talking about the diagram at 4:17. In this diagram, angles d and h are corresponding angles that are therefore congruent. Then angles g and h are supplementary angles, telling us that they add up to 180 degrees. There is no direct relationship that we've named between angles d and g, so we have to go through a couple of steps to conclude that d and g are angles that add up to 180 degrees.
@@rodger3352 The OP asked how angles d and g are related in the picture at 4:17. There is no specific name for that pair of angles. Step 1: we relate angle d to an angle in the same group as angle g. Angle d and angle h are called corresponding angles. All you need to do is translate angle d along the diagonal line, and you see it lines up perfectly with angle h. Step 2: notice that angles g and h are arranged such that they add up to a straight angle. This means they are supplementary angles, which implies they add up to 180 degrees. So if we know angle h, then we also know angle g, because g = 180 deg - h. Putting together steps 1 and 2, we see that these steps together imply that g = 180 deg - d.

I had a little bit of trouble understanding this lesson, but when I actually did the work with what you taught us, it just clicked for me. Thank you!
Thank U so much U have cleared all my doubts (*watching this video after six years*)
Solution to the question:
(3x+10) + (x-30) = 180
Open the brackets
3x+10+x-30 = 180
Like terms
3x+x+10-30 = 180
Simplify
4x-20 = 180
Exchange terms
180+20= 4x
Simplify
200=4x
Divide
x=50
Hope this helps!
thank you! 🙏

Heyyyg ❤❤❤❤
I am preparing for SAT at home. Lmao! Best decision ever!
I still don’t get it why x= 50
(3x+10)+(x-30) and since it's supplementary it's 180 degrees;
combine like terms
4x-20=180
then add +20 to twenty and 180, and that will equal to
4x=200
and divide them by 4, it will equal to
x=50

also the test is 4 grades so wish me luck
You look so funny in the beaging😁
be careful what you say on youtube, it could easily get on onto r/youngpeopleyoutube
Took me an hour to watch this cause mom wanted me to do extra credit instead of my actual work
I dont understand the checking comprehention part can somone explain.
There's two angles with algebraic definitions. You ask yourself what's the relationship between them?
Are they?
Vertical angles (nope)
Adjacent angles (nope)
Alternate interior angles (nope)
Alternate exterior angles (nope)
Same side interior angles (nope)
Corresponding angles (nope)
Complementary angles (nope)
Unfortunately, they don't apply to any of these. However, both are vertical angles to other angles.

10 - 30 = -20, watch your subtraction! so 4x = 200, x = 50.
