Question

find x and y please answer​

Answer 1

Answer:

y + 120 = 180

or, y = 180-120

or, y = 60

Now in the ∆,

x + y + 75 = 180

or, x + 60 + 75 = 180

or, x = 180-75-60

or, x = 45

Answer 2

Answer:

y = 180 - 120 = 60°

whole tringale = 180°

x + 75 + 60 = 180

x+ 135 = 180

x= 180 - 135

x= 45
