Question

In this figure, AB || CD and m∠ 4 = 85º.
What is m ∠ 5?
Enter your answer in the box.

Answer 1

m∠5=95°

Explanation:

Since lines AB and CD are parallel to one another, the angles along the lines will be the exact same as the ones above. m∠4=85° and so does m∠8.

Angle 5 and angle 8 are supplementary to one another because they are on a straight line. Subtract 85 from 180 to get 95.

96° is the measure of angle 5.
