What is the reason for the third step in this proof?
given: a || b, and both lines are cut by transversal t.

pls. see attachment.

Step: 3

Reason:Alternate interior angles theorem.

Step-by-step explanation:

We are given that

and both lines are cut by transversal t.

We have to find third step in proof.

Proof:

Step 1:

Reason :Given

Step 2:

Reason: Verticale angles theorem.

Step: 3

Reason:Alternate interior angles theorem.

Step 4:

Reason: Transitive property of congruence

Step 5:

Reason:Vertical angles theorem

Step 6:

Reason:Transitive property of congruence.

Hence, proved

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

m∠a is 90°

m∠b is 40°
