Answer:
m∠4=70°
Explanation:
Given: It is given that a and b are parallel lines cut by transversal f and the measure of ∠1 is 110°.
To find: The measure of the ∠4.
Solution: It is given that a and b are parallel lines cut by transversal f and the measure of ∠1 is 110°.
From the figure drawn,
(Linear pair)


Also,
(Corresponding angles)
Thus, the measure of the angle 4 is 70°.
