Question

what is the value of v?

Explanation:

Step1: Identify angle - sum property

The three angles shown form a right - angle (90°).

Step2: Set up equation

Let the angle be \(v\). We know that \(30^{\circ}+v + 0^{\circ}=90^{\circ}\) (the small non - labeled angle next to \(v\) is \(0^{\circ}\) as per the problem setup).

Step3: Solve for \(v\)

Subtract 30° from both sides of the equation \(v=90^{\circ}- 30^{\circ}\).

Answer:

\(60^{\circ}\)
