Answer 1

Answer:

x = 126 , y = 54 , z = 126

Step-by-step explanation:

y:z = 3:7

let's take y= 3a and z= 7a

according to figure

y+z = 180°

=> 3a + 7a = 180

=> 10a = 180

=> a = 180/10 = 18

=> y = 3.18 = 54°

=> z = 7.18 = 126°

according to figure

x+ y = 180

=> x + 54 = 180

=> x = 180 - 54 = 126°

Answer 2

Step-by-step explanation:

angle z=angle dqp (corresponding angle)

angle dqp+angle y=180°( straight line=180°)

therefore,

let angle y and angle z be 3a and 7a respectively

so,

3a+7a=180°

10a=180°

a=180\10

a=18

and,

z=7a

z=7×18

z=126°

and,

z=x( alternate interior angle)

therefore

x=126°
