Question

find x and y . i will mark you brainliest​

Answer 1

Answer:

x=60,y=60

Step-by-step explanation:

angle ACB = 180-120=60[ANGLES ON A STRAIGHT LINE] angle x+y = 120 [Exterior angle property of a ∆]

angle y = angle ACB [Congruency]

Angle y = 60

angle x + 60 + 60 = 180 [Angle Sum property of a ∆]

angle x = 180 - 120 = 60

Answer 2

Let the 3rd angle be z

z + 120° = 180°

z = 180° - 120°

z = 60°

x = 180° - 120°

x = 60°

x + y + z = 180°

60° + 60° + y = 180°

y + 120° = 180°

y = 180° - 120°

y = 60°

Therefore, x=60°, y=60°, z=60°
