The measure of an angle is 134º. What is the measure of its supplement? A. 32° B. 44⁰ C. 46⁰ D. 74⁰​
natulia [17]

Answer:

C. 46°

Step-by-step explanation:

The supplement of an angle is the other angle that makes the two angles add up to 180°. In other words, supplementary angles are angles that add up to 180°.

  • This means that 134 + x = 180

To find the measure of its supplement, we subtract 134 from 180, and then we get the angle measure.

  • 180 - 134
  • 46

Therefore, the answer is C. 46°.
