Question

what is the value of y?

Explanation:

Step1: Assume the angle is part of a right - angled situation

If the angle adjacent to \(y\) and \(y\) together form a right - angle (90°).

Step2: Use angle subtraction formula

We know that if the sum of two angles is 90° and one angle is 35.2°, then \(y = 90^{\circ}-35.2^{\circ}\).
\[y=90 - 35.2=54.8^{\circ}\]

Answer:

54.8
