Answer:
x = 20
Step-by-step explanation:
∠A + ∠B + ∠C + ∠D = 360 ( Angle Sum Property of a Quadrilateral )
(4x- 5) + (5x+5) + (3x+60) + (3x) = 360
4x- 5 + 5x+5 + 3x+60 + 3x = 360
15x + 60 = 360
15x = 360 - 60
15x = 300
x = 300/15 = 20
Substitute the value of 'x' i.e 20 to find the measure of the angles
