The angles of a quadrilateral are (x + 10)o, 2yo, 90o and (100 – y)o,…

The angles of a quadrilateral are (x + 10)^o, 2y^o, 90^o and (100 – y)^o, Find y in terms of x

A.
y = 160 + x
B.
y = 100 + x
C.
y = 160 – x
D.
y = x – 100

Correct Answer: Option C

Explanation

Sum of the angles in a quadrilateral = 360^o
(x + 10^o) + 2y + 90^o + 100 – y = 360^o
x + y + 200 = 360^o
y = 360 – 200 – x
y = 160 – x
