Question

what is the value of c? 45° c

Explanation:

Step1: Use the property of supplementary angles

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

Step2: Solve for \(c\)

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

Answer:

\(135\)
