Question

what is the value of w?

Explanation:

Step1: Recall angle - sum property

The sum of angles in a right - angled situation (where one angle is 90°) is considered. Here, the sum of the two non - right angles is 90°.

Step2: Set up the equation

Let the unknown angle be \(w\). We know that \(w + 50^{\circ}=90^{\circ}\).

Step3: Solve for \(w\)

Subtract 50° from both sides of the equation: \(w=90^{\circ}- 50^{\circ}\).

Answer:

\(40^{\circ}\)
