Complement angles equal 90 degrees, therefore
90 = larger (x) + smaller (x-25)
90 = x + x - 25
90 = 2x - 25 (add 25 to both sides)
90 + 25 = 2x or 115 = 2x
divide both sides by 2
x = 57.5 degrees (larger angle)
smaller angle = larger angle - 25
smaller = 57.5 - 25 = 32.5 degrees
Answer 32.5 degrees

Let x = the angle, then 90-x is the complement
x = (90-x) - 20 = 70-x
2x = 70
x = 35 degrees

As the question was originally phrased, 35 degrees. With the revision, 32.5 degrees.

Smaller angle is 32.5 degrees. Larger angle is 57.5

20 degrees, I think... if I understood it properly

x=[(90-x)-20]
x=90-x-20
2x=70
x=35*
