Dominick Mckinney · Answer 1

25 degrees.

Step-by-step explanation:

The 3 angles in a triangle add up to 180 degrees therefore:

m < C = 180 - 72 - 83

= 180 - 155

= 25 degrees.

Xander Oneill · Answer 2

25

Step-by-step explanation:

Theorem:

The sum of the measures of the interior angles of a triangle is 180 degrees.

The theorem is can be written as the equation below.

m
We know the measures of angles A and B, so we substitute the values for those measures, and we solve for the measure of angle C.

72 + 83 + m
Add like terms on the left side.

155 + m
Subtract 155 from both sides.

m
