Answer:
m∠ CGD = 22°
Explanation:
In the figure attached, m∠CGD = 4x + 2, m∠DGE = 3x - 5 and ,m∠ EGF = 2x + 10
Now it is given in figure, m∠DGE ≅ m∠EGF
Now we equate the values of angles
3x - 5 = 2x + 10
3x - 2x = 10 - 5
x = 5
∠CGD = 4x + 2
for x = 15
∠CGD = 4×15 + 2
= 60 + 2
= 62°
Therefore, m∠CGD = 62° is the answer.
