Question

Two parallel lines, e and f, are crossed by two transversals. What is the measure of <15? m<15 = 77° m<15 = 83° m<15 = 93° m<15 = 97°

Answer 2

The correct option is 4.

Step-by-step explanation:

Given information:
`e\parallel f` and
`\angle 10=97^(\circ)`.

If a transversal line intersects two parallel lines, then alternate exterior angles are same.

In the given figure line e and f are parallel to each other. The transversal line d intersects the parallel lines.

Since angle 10 and angle 15 are alternate exterior angles, therefore

`\angle 10=\angle 15`

`97^(\circ)=\angle 15`

Therefore measure of angle 15 is 97 degrees and option 4 is correct.
