Question

what is the value of y? 57°

Explanation:

Step1: Identify angle - relationship

The two angles shown are complementary (sum to 90° as there is a right - angle symbol).

Step2: Set up equation

Let the two angles be \(y\) and 57°. We have \(y + 57^{\circ}=90^{\circ}\).

Step3: Solve for \(y\)

Subtract 57° from both sides of the equation: \(y=90^{\circ}-57^{\circ}\).
\(y = 33^{\circ}\)

Answer:

\(33\)
