In quadrilateral WXYZ, the measure of angle Z is 10 more
than twice the average of
the measures of the other
three angles. What is the
measure, in degrees,
of Angle Z?

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
