Question

these angles are supplementary. what is the measure of ∠x? x = ?° 140°

Explanation:

Step1: Recall supplementary - angle property

Supplementary angles sum to 180°.

Step2: Set up the equation

Let the measure of ∠x be x. Then x + 140°=180°.

Step3: Solve for x

x = 180° - 140°.
x = 40°.

Answer:

40
