A conjecture and the two-column proof used to prove the conjecture are shown. Please help 46 points

see below

Step-by-step explanation:

1. Linear Pair Postulate

This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.

2. m<ABC+ m<CBD= 180 degrees

The definition of supplementary angles is that two angles are supplementary if their measures sum to 180 degrees.

3. Substitution Property of Equality

From previous step, the 90 degrees was in place of <CBD.

4. m<ABC=90 degrees

moved 90 degrees from left side to the right.

the answer to your question a or b but i am pretty sure it is b. i hope this : )
