Answer 1

Answer:

x=70

y= 30

z= 10

Step-by-step explanation:

X + 110 = 180 since they form a straight line

Subtract 110 from each side

x+110 -100 = 180-110

x = 70

Y + 110 + 40 = 180 since the three angles of a triangle add to 180

y+150 = 180

Subtract 150 from each side

y+150-150 = 180-150

y = 30

A + B+ C = 180 since the three angles of a triangle add to 180

90 + y+z+ 40 =180

90 + 30+z + 40=180

Combine like terms

170 +z = 180

z = 180-170

z = 10
