Question

what is the value of p? 111°

Explanation:

Step1: Recall angle - pair relationship

The two angles \(p\) and \(111^{\circ}\) are supplementary (they form a straight - line).

Step2: Use the supplementary - angle formula

The sum of two supplementary angles is \(180^{\circ}\), so \(p + 111^{\circ}=180^{\circ}\).

Step3: Solve for \(p\)

\(p=180^{\circ}- 111^{\circ}\).
\(p = 69^{\circ}\)

Answer:

\(69\)
