Question

find the measure of the missing angle.
60°
a
answer
a =

Explanation:

Step1: Recall the property of right - angle

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

Step2: Set up the equation

We know that \(60^{\circ}+a = 90^{\circ}\) (since the sum of the two non - overlapping angles forming a right - angle is \(90^{\circ}\)).

Step3: Solve for \(a\)

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

Answer:

\(30^{\circ}\)
