Answer:
a = 55
Step-by-step explanation:
This angle is a right angle.
A right angle is equal to 90 degrees.
That means you have to subtract 90 and 35.
90 - 35 = 55
55° is the missing angle of the right angle.
The whole image is a right angle which is 90 degrees. So subtract 35 degrees giving you the answer of 55 degrees
