Answer 1

Answer:

72°

Step-by-step explanation:

given,

x:y=2:3

let x =2a

and y = 3a

x+y=180°(linear pair)

2a+3a=180°

5a=180°

a=180°/5

a=36

so

x=2x36=>72°

x=z=72°(alt. int. angle)

Answer 2

Step-by-step explanation:

Let angle x and y respectively 2x and 3x .

The sum of two adjacent angle is 180

2x+3x=180°

5x=180

x=180\ 5

x=36

angle x=36×2=72

y=36×3=108

angle z and x are alternate interior angle.

So , an z = 72°
