Question

find the value of unknown x and y in the given diagram​

Answer 1

Answer:

x = 80°

y = 60°

Step-by-step explanation:

y + 120° = 180° (Linear pair)

y = 180°-120°

y = 60°

x+y+40° = 180° (triangle's all angle's sum = 180°)

x+60°+40° = 180°

x+100° = 180°

x = 180°-100°

x = 80°

hope it helps.

Answer 2

Step-by-step explanation:

y + 120° = 180° (linear pair angles)

y = 180° - 120°

y = 60°

Sum of all three interior angles in triangle = 180°

x + y + 40° = 180°

x + 60° + 40° = 180°

x + 100° = 180°

x = 180° - 100°

x = 80°
