Question

please give the answer step by step​

Answer 1

Answer:

x=126°

Step-by-step explanation:

x + y=180................(1)

and y=z ( Alternate angles)

Also from the figure

y+z=180.................(2)

and given y/z=3/7

z=(7/3) *y

7y/3 +z=180

7y+3y=540

10y=540 , y=54°

Thus from(1)

x+54=180

x=180-54=126°

Answer 2

Answer:

X = 126°
