Question

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

Explanation:

Step1: Identify Vertical Angles

$\angle CGB$ and $\angle DGA$ are vertical angles. Vertical angles are equal in measure.

Step2: Apply Vertical Angles Theorem

Since $m\angle CGB = 78^\circ$, by the Vertical Angles Theorem, $m\angle DGA = m\angle CGB$.
Thus, $m\angle DGA = 78^\circ$.

Answer:

$78$
