Question

find the value of ∠a. 25 degrees 30 degrees 35 degrees 90 degrees

Explanation:

Step1: Analyze the right - angle relationship

We know that the sum of the two non - right angles in a right - angle (90°) is 90°.

Step2: Calculate the value of ∠A

Let ∠A be \(x\). We have \(x + 65^{\circ}=90^{\circ}\). Then \(x=90^{\circ}- 65^{\circ}\).
So \(x = 25^{\circ}\).

Answer:

25 degrees
