Question

If the measure of angle 1 is 68°, what is the measure of angle 5?

Answer 1

Answer:  The correct option is (B) 68°.

Step-by-step explanation:  Given that the measure of angle 1 is 68°.

we are to find the measure of angle 5.

From the figure, we note that

lines s and t are parallel to each other and r is a transversal.

So, angles 1 and 5 are corresponding angles, and their measures must be same.

That is,

$m\angle 1=m\angle 5.$

Since, we have

$m\angle 1=68^\circ.$

So, we get

$m\angle 5=68^\circ.$

Thus, the measure of angle 5 is 68°.

Option (B) is CORRECT.

Answer 2

68 degrees as well, because the angles are corresponding.
