Question:

Find the value of x and the value of y.

A.

x = 15, y = 10

B.

x = 20, y = 50

C.

x = 50, y = 10

D.

x = 50, y = 20

The image of the degrees of angles is attached below:

Option C: is the value of x and y

Explanation:

Since, we know that the vertically opposite angles are equal.

From the figure, the angles and are equal.

-----------(1)

And the angles and are equal.

         -----------(2)

Substituting in the equation , we get,

Thus, the value of y is

Substituting in the equation , we have,

Thus, the value of x is

Therefore, the value of x and y are and

Hence, Option C is the correct answer.
