Question

12. Find X + Y + Z (figure given)

diagram given at the top​

Answer 1

X=180-80=100

Z=180-40=140

Y=80+40=120

hope this helps

cheers ✌️✌️

Answer 2

Answer:

By Linear Pair,

z + 40° = 180°

z = 180° - 40°

z = 140°

By Linear Pair,

x + 80° = 180°

x = 180° - 80°

x = 100°

By Exterior Angle Sum Property,

y = 80° + 40°

y = 120°

Hope it helps you!!!!
