In the figure, r//s

< 2= < they are corresponding angles of parallel lines cut by a transversal.
< 5=< by the vertical angles theorem.

 , because they are corresponding angles of parallel lines cut by a transversal.

by Vertical angles theorem.

Step-by-step explanation:

From the given picture, we can see there are two parallel lines r and s intersected by a transversal line t.

Since corresponding angles of parallel lines cut by a transversal.

Therefore they must be equal.

Then,

Also, since are vertical angles.

Vertical angles theorem says that vertically opposite angles  at any cross section must be equal.

by Vertical angles theorem.

step-by-step explanation:

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
