Answer:
(A) y = 24
Step-by-step explanation:
Given GDEF is a parallelogram and m∠E = 108°
To find: value of y
In ║grm GDEF,
m∠D + m∠E = 180° (Consecutive angles of parallelogram are supplementary)
3y° + 108° = 180°
3y° = 180° - 108°
3y° = 72°
y = 72°/3 = 24°
Therefore, option (A) is the correct answer.
