Question

use the figure below to complete each exercise.
figure showing two intersecting lines with angles 63° and (5b - 7)°

Explanation:

Step1: Identify vertical angles

Vertical angles are equal, so \(5b - 7 = 63\).

Step2: Solve for \(b\)

Add 7 to both sides: \(5b = 63 + 7 = 70\).
Divide by 5: \(b = \frac{70}{5} = 14\).

Answer:

\(b = 14\)
