Question

plz tell how to solve this guyz
Don't tell the answer bu just tell me how to solve it​

Answer 1

Step-by-step explanation:

first assume that y and z are equal to 3a and 7a respectively.

then; x = z = 7a (alternate interior angles)

now, x + y = 180° ( co interior angle)

7a + 3a = 180°

now u can solve it further......

Answer 2

Step-by-step explanation:

$\: Given \: that$

$\:Line AB || \:Line CD || \:Line EF \:and \:Line QP$ $\:is \:the \:transversal$

$y : z = 3 : 7$

$\: let \: \angle{y} = \:3a$ $and$ $\: \angle{z} = \:7a$

$\: According \: to \: the \: question$

$\angle{y} \: + \: \angle{z} \: = \: 180°$

$( \:alternate \:angles )$

$\implies \: 3a \: + \: 7a \: = \: 180°$

$\implies \: 10a \: = \: 180°$

$\implies \: a \: = \: 18°$

$\angle{y} \: = \: 54°$

$\angle{z} \: = \: 126°$

$\angle{x} \: = \angle{z}$

$( \:alternate \:interior \:angles )$

$\therefore \angle{x} \: = \: 126°$
