Answer:
The measure of angle 5 is 68° .
Step-by-step explanation:
As given
Parallel lines s and t are cut by a transversal r.
m ∠ 1 = 68 °
Definition of Corresponding angle.
Two lines (s and t shown in the diagram) are crossed by another line (Transversal i.e r ): The angles makesin matching corners are called Corresponding Angles.
Thus
∠1 = ∠5
(By using the corresponding angle property.)
∠5 = 68 °
Therefore the measure of angle 5 is 68° .
