Answer: The measure of angle 5 is
.
Step-by-step explanation:
It is given that the AB || CD and the measure of angle 1 is
.
If a transversal line intersect two parallel line then all the corresponding angles are equal.
In the given figure the line AB || CD and one line is intersect them which is transversal line.
According to the property of transversal line,


Therefore the measure of angle 5 is
.
