Respuesta :

A.)44
The total number will equal 180. All right angles are 90. 180-90-46 equal 44

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.
