a.
Answer to Problem 60E
law of cosine is used for solving given triangle
Explanation of Solution
Given information:
Here in the given diagram three side length are given so in this case for solving triangle law of cosine is used,
Initially choose the angle to start with, then to find measure of angle given the side length, and then repeat the procedure to find out the Second angle of the triangle.
Then measure of third angle by subtracting the first two angles from
