Question

Find the value of each variable.

Answer 1

y = 107

z = 79

Explanation:

The sum of adjacent angles on a straight line is 180.

101 + z = 180

101 - 101 + z = 180 - 101

z = 79

The sum of angles in a quadrilateral is 360 degrees.

79 + 80 + 94 + y = 360

253 + y = 360

253 - 253 + y = 360 - 253

y = 107

Answer 2

z = 79 degrees
y = 107 degrees
