Answer:

143 degrees

Step-by-step explanation:

If you were taught this rule, then you would know that the two far interior angles of a triangle are equal to the one on the outside, i dont know its name, but i know it works, so all you have to do is add 90+53=143 degrees for your answer.

angle B=90
90+53 (angle 53) = 143
all triangles angles always add up to 180
180-143=37
angle C=37
180-37=143
Answer is A
