Question

what is ( mangle g )?( mangle g = square^circ )

Explanation:

Step1: Recall cyclic quadrilateral rule

Opposite angles sum to $180^\circ$.

Step2: Set up angle equation

$m\angle E + m\angle G = 180^\circ$

Step3: Solve for $m\angle G$

$m\angle G = 180^\circ - 103^\circ$

Answer:

$77^\circ$
