Find the area of the triangle.

Question

b=125
c=162
<B=40
(b and c are the sides)
(<B is the angle)

Answer 1

Use the law of sines to solve for <C.
(sin <C)/c = (sin <B)/b

Use <A + <B + <C = 180 to solve for <A

Uze the law of sines to solve for a.

The triangle area is (1/2) c sin B * a

Answer 2

I worked it out. Can you tell me if these are right.
<C=56.4 degrees
<A=83.6 degrees
Area=10095.2
We have to round to the nearest tenths.
