Question

find the measure of the missing angle.
answer attempt 1 out of 2

Explanation:

Step1: Recall the sum of angles in a right - angled configuration

The sum of angles in a right - angled (90°) configuration is 90°.

Step2: Calculate the missing angle \(a\)

We know that \(a + 55^{\circ}=90^{\circ}\). So, \(a = 90^{\circ}- 55^{\circ}\).

Answer:

\(35^{\circ}\)
