Question

10.
find the measure of the missing angle.

Explanation:

Step1: Recall triangle angle sum property

The sum of angles in a triangle is \(180^{\circ}\).

Step2: Identify known angles

One angle is \(90^{\circ}\) (right - angle) and another is \(40^{\circ}\).

Step3: Calculate the missing angle

Let the missing angle be \(x\). Then \(x = 180^{\circ}-90^{\circ}-40^{\circ}\).
