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
Answer:
The correct answer is:
155 °
Step-by-step 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°.
