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 1

I would say m<15 is 97 because they are alternating exterior which makes them corresponding angles
the answer is m<97

Answer 2

Answer:

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.
