Question

GIVING MEDALS
if A= 42.2 degrees, B=13.6 degrees and a=41.3, find the area of triangle ABC

Answer 1

Do you know how to use the Cosine law?

Answer 2

you don't have the height yet, so the best would be to find all angles and all sides.
After you find the sides do the followingknowing all the sides, and using a^2+b^2=c^2,

Answer 3

but you only know one side

Answer 4

Continuing from what I said.
FIND ALL SIDES FIRST, using the LAW of COSINES.


Where two bases are going to be (b-y) and y
so you would get

Answer 5

After finding all sides, you can find the height.

A= 42.2 degrees, B=13.6

so angle C= 180-(42.2+13.6)=124.2


X would be your height, then
