Ok so these are the answers that I can choose~ (Please and thank you <3)
A.44°
B.134°
C.90°
D.34°

Answer:
44 degrees, or A is your answer.
Step-by-step explanation:
You know angle A which is 46 and angle C which is 90, now all you have to do is solve to find angle B.
90+46=136
All the sides have to add up to 180 so simply do 180 - 136.
That will get you 44.
