Question

if m∠cgb = 78°, then what is m∠dga? answer attempt 1 out of 2 m∠dga =

Explanation:

Step1: Identify vertical - angles

$\angle CGB$ and $\angle DGA$ are vertical - angles.

Step2: Apply vertical - angle property

Vertical angles are congruent. So, $m\angle DGA=m\angle CGB$.

Step3: Substitute the given value

Since $m\angle CGB = 78^{\circ}$, then $m\angle DGA=78^{\circ}$.

Answer:

$78$
