Question

1. find the measures of the indicated angles.

Explanation:

Step1: Recall angle - sum property of a right - angle

The right - angle is 90°. The sum of the two non - right angles in a right - angled triangle (or in this case, the two angles that make up the right - angle) is 90°.
Let the two angles be 65° and \(b\). So, \(65^{\circ}+b = 90^{\circ}\).

Step2: Solve for \(b\)

Subtract 65° from both sides of the equation \(65^{\circ}+b = 90^{\circ}\).
\(b=90^{\circ}- 65^{\circ}\)

Answer:

\(b = 25^{\circ}\)
