Answer:
44°
Explanation:
First, we solve for x.
x + 59 + 84 + x + 51 = 180 (since all angles in a triangle add to 180)
2x + 194 = 180
2x = -14
x = -7
Now, we solve for the bottom right angle which is angle A. (x+51)
x + 51 = -7 + 51 = 44
Therefore, angle A is 44°.
(Although it can be confusing which angle A is referring to since it could also refer to the reflex angle)
