Question

△ABC∼△EFG.
Given m∠A=39° and m∠F=56°, what is m∠C?

Answer 1

x=85

Explanation:

let's angle c be x

39+56+x=180

95+x=180

x=180-95

x=85

Answer 2

85 degrees

Explanation:

In similar triangles, corresponding angles are congruent, or have the same measure.

Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.

A+b+c=180

39+56+c=180

c=85 degrees.
