Could anyone help me find the missing value of W, X,Z, and Y ?

x= 50°

w= 130°

y°= 110°

z°=30°

Step-by-step explanation:

x°= 180° - 60°- 70° ( angle sum of triangle)

= 50°

w°= 180° - 50° ( adjacent angles on a straight line)

= 130°

y°= 180° - 70° ( adjacent angles on a straight line)

= 110°

z°= 180 - 40° - 110° ( angle sum of triangle)

= 30°

make sure you have version 2.50

try looking in the very back of the book : )
