Question

what is the value of d?

Explanation:

Step1: Identify angle - relationship

The large angle of \(77^{\circ}\) is composed of an angle of \(26^{\circ}\) and angle \(d\).

Step2: Set up subtraction formula

We use the formula \(d = 77^{\circ}-26^{\circ}\).

Step3: Calculate the value of \(d\)

\(d=77 - 26=51^{\circ}\)

Answer:

\(51\)
