Question

Given m||n, find the value of x.
135

Answer 1

Answer: Option C.

Explanation:

Let as consider the complete question is same as question shown in the below figure.

In the figure m║n.

If a transversal line intersect two parallel lines then same sided interior angles are supplementary angles and their sum is 180 degrees.

`3x+x=180^(\circ)`

`4x=180^(\circ)`

Divide both sides by 4.

`x=(180^(\circ))/(4)`

`x=45^(\circ)`

The value of x is 45 degrees.

Therefore, the correct option is C.
