Question

Find the value of x and y.

Answer 1

X=70

Y=90

Explanation:

Hello! First you need to find X, you need to subtract 180 by 110 due to the supplementary angle rule, which is all angle that is on a flat line must add up to 180 degrees. To find Y, you must subtract 360 by 270. The reason you do this is because all angles in a quadralatical shape must equal 360.

TL;DR

110+X=180

X=70

270+Y=360

Y=90

Answer 2

x = 70, y = 90

Explanation:

A straight line is equal to 180 degrees, so if 180 is split between 110 and x. Subtract the 110 to get the rest. 180-110 = 70.

All sides in a quadrilateral add up to 360 degrees, add all of the remaining angles (112+88+70) to get 270. 360-270 = 90 degrees. Y is 90 degrees.
