If you know what "complementary angles" means,
then you can do this one in your sleep. If you don't,
then you can't do it at all.
"Complementary angles" means two angles
that add up to 90 degrees.
(32 degrees) + (the angle you don't know) = 90 degrees
Subtract 32 degrees from
each side of this equation:
(the angle you don't know) = (90 degrees) - (32 degrees)
(the angle you don't know) = (90° - 32°) = 58 degrees
