Question

examine the triangle below. which equation can be used to determine the measure of ∠x? a. 125−90=x + 180 b. 125 + x=180 c. 180−x=90 d. 125 + 90=180−x

Explanation:

Step1: Use the property of adjacent angles on a straight line

Adjacent angles on a straight line sum to \(180^{\circ}\).
\(x + 125=180\)

Answer:

B. \(125 + x = 180\)
