Find y of this shape.

Phantasy [73]

Answer:

y = 75

Step-by-step explanation:

The sum of the angles in a quadrilateral = 360°

∠DGF and 80° form a straight angle and are supplementary, hence

∠DGF = 180° - 80° = 100°

Subtract the sum of the 3 angles from 360 for the value of y

y = 360 - (65 + 120 + 100) = 360 - 285 = 75
