PLS HELP MEEEEEEEEEEEEEEEEEE!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:
c
Step-by-step explanation:
a is not enough information because the measure of angle 2 could be another random value
b is not correct for the same reason as a
d is not correct because those two angles do not equal 90
c is correct because of a theorem, so basically if you have two angles, and they have segments at 90 angles placed in the specified spots, they are on the bisector
