Question

find the measure of the missing angles.
answer attempt 1 out of 2
$g=square^{circ}$ $h = square^{circ}$

Explanation:

Step1: Use vertical - angle property

Vertical angles are equal. Angle \(h\) and the \(123^{\circ}\) angle are vertical angles. So \(h = 123^{\circ}\).

Step2: Use linear - pair property

The sum of angles in a linear - pair is \(180^{\circ}\). Angle \(g\) and the \(123^{\circ}\) angle form a linear - pair. So \(g=180 - 123\).
\(g = 57^{\circ}\)

Answer:

\(g = 57^{\circ}\), \(h = 123^{\circ}\)
