Question

Is the answer a=213 because a angle look like a acute

Answer 1

a = 57°

Step-by-step explanation:

To determine the missing angle, we would solve for it

The angle is right angled (it is represented by the small square). Hence, it is at 90 degrees.

33° + a = 90°

subtract 33 from both sides:

33 - 33 + a = 90 - 33

0 + a = 57

a = 57°
