Given: lines l and m are parallel, and line t is a transversal.
angle pair result/justification
1 and 2 are equal (vertical angles)
6 and 8 are equal (corresponding angles)
1 and 4 are equal (alternate exterior angles)
4 and 8 are supplementary angles (i.e. add up to 180 degrees, a straight angle)
Note:
alternate angles are on opposite sides of the transversal, and each attached to a different (parallel) line.
If they are both enclosed by the parallel lines, they are alternate interior angles (examples: angles 2 and 3, 6 and 7)
If they are both outside of the two parallel lines, they are alternate exterior angles (examples: angles 1 and 4, 5 and 8)

Answer:13 revolution
Step-by-step explanation:
Given data
Wheel initial angular velocity
=18 rad/s
Contant angular deaaceleration
=2
Time required to stop wheel completely=t sec
0 =18 +
t=9 sec
Therefore angle turn in 9 sec
=
+
=
+
=81rad
therefore no of turns(n) =
n=12.889
13 revolution
