Question

what is the value of p?

Explanation:

Step1: Identify angle - type relationship

The two angles are adjacent and form a straight - line. The sum of adjacent angles on a straight - line is 180°.

Step2: Set up an equation

Let the given angle be 57.5°. We have the equation $p + 57.5^{\circ}=180^{\circ}$.

Step3: Solve for p

Subtract 57.5° from both sides of the equation: $p=180^{\circ}-57.5^{\circ}$.
$p = 122.5^{\circ}$

Answer:

$122.5$
