Question

find the measure of the missing angles.

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. Angle \(e\) and the \(134^{\circ}\) angle are vertical angles. So \(e = 134^{\circ}\).

Step2: Use linear - pair property

The sum of angles in a linear pair is \(180^{\circ}\). The \(134^{\circ}\) angle and angle \(f\) form a linear pair. So \(f=180 - 134=46^{\circ}\).

Step3: Identify right - angle

The square symbol indicates that \(d = 90^{\circ}\).

Answer:

\(d = 90^{\circ}\), \(e = 134^{\circ}\), \(f = 46^{\circ}\)
