Question

In trangle ABC, suppose a=8, b=16, and angle C = 135 degrees. Find Side C

Answer 1

c = 22.38

Explanation:

To find the value of c, given the angle that faces it, we use the cosine rule

We have it in its general form as;

c^2 = a^2 + b^2 - 2ab Cos C

c^2 = 8^2 + 16^2 -2(8)(16)cos 135

c^2 =501.02

c = √501.02

c = 22.38
