126 deree................... ....

Answer 2

y : z = 3 : 7

Let y = 3a
z = 7a


Here y + z = 180°
3a + 7a = 180°
10a = 180°
a = 180/10
a = 18°

y = 3(18) = 54
z = 7(18) = 126

we can find x value in two ways,
(1)
x + y = 180°
x + 54 = 180°
x = 180-54
x = 126

(2)
x = z (alternate interior angles)
x = 126°
