Question

find the measure of angle x y z​

Answer 1

Step-by-step explanation:

y = 80°

(linear pair)

x+y = 140° (exterior angle property)

x = 140-80

x = 60°

z = 40°

(linear pair)

Answer 2

Answer:

Z=40° because

140° + Z = 180° (Linear pair )

Y=80° because

100° +Y =180° (Linear pair)

X=40°because

X+Y+Z =180°because

sum of three angles in a triangle is 180°

X+Y+Z=180°

X+80°+40°=180°

120°+X=180°

Moves X to right side

X=180°-120°

X=60°
