Match the justifications for each step in order to prove the Alternate Interior Angles Theorem. Note that lines p and q are para
Alex_Xolod [135]

Answer:

Option (3)

Step-by-step explanation:

There are two parallel lines 'p' and 'q' and a transversal line is intersecting these lines at two distinct points.

Each pair of angles formed on the inner side of the parallel lines but opposite sides of the transversal line are the alternate interior angles.

Pair of angles (∠2 and ∠6) and (∠3 and ∠7) are the alternate interior angles.

Since, alternate interior angles are equal in measure,

∠2 ≅ ∠6

∠3 ≅ ∠7

Option (3) will be the answer.

Math I NEED HELP LOOK AT THE IMAGE ALGEBRA IS KILLING ME
MA_775_DIABLO [31]

Answer:

22.5

Step-by-step explanation:

Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:

13.5 / 0.6 = 22.5

22.5 x 0.6 = 13.5
