lets x be the angle the complement is 90-x
you write 90-x =x+25
90-25 =2x x =65/2 = 32° 30'
and the complement is 57°30'

let one angle be x. then the other angle is 25 degrees less, so it's x-25. complementary angles add up to 90 degrees, so (x) + (x-25) = 90
x+x-25=90
2x-25 = 90
2x = 115
x = 115/2 = 57.5
the other angle is then 57.5 - 25 = 32.5,and that's the smaller angle

Two angles are complementary if they add up to 90 °.
90=(x+25)+x
I leave the rest to you.

x = (90° - x) - 25°
2x = 65°
x = 32.5°

x+ (x+25)=90
solve for x
-25=-25
x+x=65
2x=65
/2 /2
x= 32.5
