Paul M. · Accepted Answer

The area of a triangle is (1/2) of the product of any two sides times the sin of the angle between them.

When you are given 2 angles you immediately have the third and you need to use the law of sines to get the other side you need.

In part c you need to use the law of sines to get a 2nd angle, then you will have the third angle also

Make sure you draw a figure for EACH part.
