Question

9 multiple choice 1 point write the supplements of these angles. 129° 39° 51° 52° 50°

Explanation:

Step1: Recall the definition of supplementary angles

Supplementary angles add up to \(180^{\circ}\).

Step2: Calculate the supplement

Let the supplement of \(129^{\circ}\) be \(x\). Then \(x + 129^{\circ}=180^{\circ}\), so \(x = 180^{\circ}- 129^{\circ}\).

$$x=180 - 129=51^{\circ}$$

Answer:

\(51^{\circ}\) (the second option)
