Question

what is the value of d?
none of these
125
145
135

Explanation:

Step1: Use the property of supplementary angles

Supplementary angles add up to \(180^{\circ}\).
If one angle is \(45^{\circ}\), then \(d + 45^{\circ}=180^{\circ}\).

Step2: Solve for \(d\)

Subtract \(45^{\circ}\) from both sides of the equation: \(d=180^{\circ}- 45^{\circ}\).
\(d = 135^{\circ}\)

Answer:

135
