Question

find x.
8.
(x - 15)°
90°
x =

Explanation:

Step1: Identify angle relationship

The angle \((x - 15)^\circ\) and \(90^\circ\) are equal (vertical angles or corresponding angles from parallel lines, here they are equal as they are alternate interior or vertical in this intersection setup). So we set up the equation:
\(x - 15 = 90\)

Step2: Solve for \(x\)

Add 15 to both sides of the equation:
\(x = 90 + 15\)
\(x = 105\)

Answer:

\(105\)
