Question

in the following figure find X and y​

Answer 1

Answer:

x=60°

Step-by-step explanation:

By exterior angle theorem

60°+ x=120°

x=120-60

x=60°

Answer 2

Answer:

Let the adjacent angle of 120 be y

$y + 120 = 180 \\ y = 180 - 120 \\ y = 60$

$x + y + 60 = 180 \\ x + 60 + 60 = 180 \\ x + 120 = 180 \\ x = 180 - 120 \\ x = 60$
