Question

The measure of an angle is 25 degrees what is the measure of its supplementary angle

Answer 1

The correct answer is:

155 °

Explanation:

Supplementary angles have measures that add to 180°.

ABC and CBD are supplementary angles.

solve

Since the angles are supplementary, their measures must add to 180°. Set up an equation and solve for n.

n + 25° = 180°

n + 25° − 25° = 180° − 25°

n = 155°

The measure of the supplementary angle is 155°.

Answer 2

The answer would be 50 because in order to find the measure of a supplementary angle,you have to multplify it's radius or diameter by2
