Question

Given rs || qp, what is the value of x?

Answer 1

In the given figure,

Angle 108° + 12x = 180°

because they for pair of co- interior angles which are supplementary.

so,

• $12x + 108\degree = 180\degree$

• $12x = 180\degree - 108\degree$

• $12x = 72\degree$

• $x = \dfrac{72\degree}{12}$

• $x = 6\degree$

hence , value of x = 6°

Answer 2

Answer:

$12x + 108 = 180 \\ \\ 12x = 180 - 108 \\ \\ 12x = 72 \\ \\ x = \frac{72}{12} \\ \\ x = 6$

it's is a co - inter angle they sum are 180
