Question

(c) Find the value of x and y in the given figure.
​

Answer 1

Answer:

y= 60°

x = 70°

Step-by-step explanation:

y + 120° = 180°

y = 180° - 120°

y = 60°

y + x + 50° = 180°

60° + x + 50° = 180°

110° + x = 180°

x = 180° - 110°

x = 70°

Answer 2

Step-by-step explanation:

exterior angle = 120

interior angle = 50

so sum of interior angle = y - 120 = 180

y = 180 - 120 = 60

so, value of y = 60

x + 60 + 50 = 180

x = 180 - 110

x = 70
