Question

lines a and b are parallel and lines e and f are parallel. what is the value of x? 8 82 98 172

Explanation:

Step1: Use property of parallel lines

When two parallel lines are cut by a transversal, corresponding - angles are equal. Since lines $a$ and $b$ are parallel and lines $e$ and $f$ are parallel, the angle of $98^{\circ}$ and the angle with measure $x^{\circ}$ are corresponding - angles.

Step2: Set up the equation

By the corresponding - angles postulate, we have $x = 98$.

Answer:

C. 98
