Step-by-step explanation:
We are given the following information:
Two parallel lines are crossed by a transversal.
The attached image shows the intersection of transversal and the angles.

Thus, y = 50 degree
Answer:
A motor running at 75 revolutions per second.
Step-by-step explanation:
Given statement: A motor running at 4500 RPM, revolutions per minute.
⇒ In one minute , a motor running at 4500 revolutions.
Use conversion:
We have to calculate how many revolutions per second.
in 60 sec , a motor running at 4500 revolutions
then,
in 1 sec , a motor running at revolutions.
Therefore, a motor running at 75 RPS, revolution per second.
