Question

In AABC, the measure of A is 108° and the

measure of B is 38° . What is the measure of
C?

Answer 1

Should be 34

Explanation:

Answer 2

∠C=34

Explanation:

The interior angles of a triangle add to 180 degrees, so

∠A +∠B+ ∠C=180

We know that ∠A is 108, and ∠B is 38, so we can substitute them in

108+38+∠C=180

Combine like terms by adding 108 and 38

146+∠C=180

Subtract 146 from both sides

∠C=34
