Question

Two parallel lines are crossed by a transversal. What is the value of x?

Answer 1

x=115

Because S & T are parallel lines. So line t crossing through both of them give you them same values for corresponding parts.

Answer 2

Answer:

The correct option is 4.

Step-by-step explanation:

If a transversal line intersect two parallel lines then the corresponding angles are congruent.

From the given figure it is clear that the transversal line t intersect the two parallel lines r and s. So, x° and 115° are corresponding angles because they have same relative position at both intersections.

$x^{\circ}=115^{\circ}$

On equating both the sides we get

$x=115$

The value of x is 115, therefore the correct option is 4.
