Question

what is the value of b?
none of these
25
35
45

Explanation:

Step1: Use the property of adjacent angles

Adjacent angles sum to \(180^{\circ}\). So, \(b + 135^{\circ}=180^{\circ}\).

Step2: Solve for \(b\)

Subtract \(135^{\circ}\) from both sides: \(b = 180^{\circ}- 135^{\circ}\).

Answer:

\(b = 45^{\circ}\), so the answer is \(45\).
