Question

use theorems about perpendicular lines to find the value of x in the given figure. the value of x is 19 (do not include the degree symbol in your answer)

Explanation:

Step1: Recall perpendicular - angle property

Perpendicular lines form a 90 - degree angle.

Step2: Set up an equation

We know that \(x + 71=90\).

Step3: Solve for x

\(x=90 - 71\).

Answer:

19
