Question

if angle x and angle y form a pair of alternative angles, if x=60 , then y =

Answer 1

Answer:

120°

Step-by-step explanation:

Sum of alternative angles is 180°

x + y = 180

Then y = 180 - 60 = 120°

Answer 2

Answer:

y=120

Step-by-step explanation:

Given: X and Yare alternate interior angles

X=60

To find : Y =?

We know that the sum of two alternative angles =180

Therefore;

x+y =180

60+y=180

now Transposing 60° from left hand side to right side

y =180-60

y=120°
