Question

solve for x. 61° (x + 9)°

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. The angle with measure $(x + 9)^{\circ}$ and the angle with measure $61^{\circ}$ are vertical angles. So we set up the equation $x+9 = 61$.

Step2: Solve for x

Subtract 9 from both sides of the equation $x+9=61$. We get $x=61 - 9$.

Answer:

$x = 52$
