Question

find the measure of the missing angle. answer attempt 2 out of 2 a =

Explanation:

Step1: Recall angle - sum property of right - triangle

In a right - triangle, one angle is 90° and the sum of all interior angles is 180°. Let the missing angle be \(a\), and the given non - right angle is 25°.

Step2: Set up the equation

We know that \(a + 25^{\circ}+90^{\circ}=180^{\circ}\). Then \(a=180^{\circ}-(90^{\circ} + 25^{\circ})\).

Step3: Calculate the value of \(a\)

First, calculate \(90^{\circ}+25^{\circ}=115^{\circ}\). Then \(a = 180^{\circ}-115^{\circ}=65^{\circ}\).

Answer:

\(65^{\circ}\)
