Explanation:

Step1: Identify triangle type

$\triangle GHE$ is isosceles, $EG = EH$ (radii of the circle).

Step2: Find base angles

$\angle G = \angle H = 36^\circ$

Step3: Calculate $\angle GEH$

Use angle sum of triangle:
$$m\angle GEH = 180^\circ - 36^\circ - 36^\circ = 144^\circ$$

Answer:

144
