Question

what is the value of v? 28° 48° v

Explanation:

Step1: Identify angle - addition relationship

The large angle is composed of two non - overlapping angles. The measure of the large angle is the sum of the measures of the two smaller angles. So, $v+28^{\circ}=48^{\circ}$.

Step2: Solve for $v$

Subtract $28^{\circ}$ from both sides of the equation: $v = 48^{\circ}-28^{\circ}$.

Answer:

$20^{\circ}$
