I'm confused on the area we found it was 5364 but on the short distance on area you wrote 5360 why is that am confused but on the whole explanation it was clear
How came it's 119.9 ad not 119 coz they have not given us if it's to how many decimal figures ad the rules of the first page says if degree of accuracy is not specified in the question ad if the answer is not exact give the answer in three significant figures. Or give in degrees to one decimal place
Well thought sir thank you so much am now understanding this topic correctly
Well explained sir
❤❤❤ thank you Sir for this broadcast on TH-cam I really understand this, please do more am subscribing now
Well explained sir may God bless you
Great explanation sir

Thank you sir for your time for us. May Almighty God bless and reward you
Mr there are two formulas the one you've used and the other one you start with cos, are they the same or they are different
Prof, i thought that area of a non right angled triangle with given sides is calculated via Heroes formula?
Wonderful sir
Thanks
@@jacobsichambaonlinemath5090 Why not just 5363..But u said 5360??
But sir we have to round off 119.9 so that we come up with 120
Nice
how did u find a common denominator
Thanks
I like this
On dividing cos -24750 could you please explain on that
Am getting you sir
Sr. Angle BAC the is error for the Answer as I was trying to solve.

How did you find 1800 as a common denominator
Multiple 8×225=1800
Confused on the final answer when finding the angle
❤❤❤❤
I would like to be your student.
Sir how do you know that it's cosine
Hi sir, when i calculated 9000-77650 it gave me -68650 am confused
You calculated 9000 instead of 90000 that's why you got -68650 instead of 12350 because remember 300²=90000 not 9000.
More plz
Helpful
Thanks 🙏
How can I join
Can you round off 119.9 to 120 as a whole number
Yes
Sorry but I never understood how u found area coz ...
I'm confused where we did we get 2bc 🙃
Thats the cosine rule formula for when finding an angle in a triangle. Hope this helps. Good luck 😊
Sir write big solving I can't see
Please why have you put something on the A and what is the name for that
Can you please help me to understand why we used cos at first and for area were using the sin
How did you know that it's cosine
It has all three sides but no angle
Sorry sir question b am behind
How can I know that this question need cosine rule?
If you are given all the sides then you use cosine rule
If you are given all the sides and the triangle is not a right angle triangle, use cos rule.
Can I us any method of my choice
So far that's it unless otherwise.
240 and not 120
I don't understand on question b...
I'm confused sir isn't cos inverse -0.4989898999 not 133.25 coz that's what my calculator says or there is a mistake
Your calculator is not in degrees
