Correct Answer: Option C
Explanation:
Sum of the angles in a quadrilateral = 360o
(x + 10o) + 2y + 90o + 100 - y = 360o
x + y + 200 = 360o
y = 360 - 200 - x
y = 160 - x
Sum of the angles in a quadrilateral = 360o
(x + 10o) + 2y + 90o + 100 - y = 360o
x + y + 200 = 360o
y = 360 - 200 - x
y = 160 - x
