Chapter 11.1, Problem 39STP

To determine

To find: Value of $x$

Answer to Problem 39STP

Option C is correct.

Value of $x$ is ${75}^0$

Explanation of Solution

Given information:

Angles are $x^0$ and ${75}^0$

From the given figure

We can say that

Angles ${75}^0$ and $x^0$ are alternate interior angles.

WE know that alternate interior angles are congruent

So,

  $x^0={75}^0$

Therefore,

Value of $x$ is ${75}^0$
