Question

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

Explanation:

Step1: Recall the property of right - angle

A right - angle measures \(90^{\circ}\).

Step2: Set up the equation

Let the missing angle be \(a\). We know that \(60^{\circ}+a = 90^{\circ}\) (since the two angles form a right - angle).

Step3: Solve for \(a\)

Subtract \(60^{\circ}\) from both sides of the equation: \(a=90^{\circ}-60^{\circ}\).

Answer:

\(30\)
