I just need to know if I answered this correctly.

mLy=37 find the complementary angle Ly

That would be 90-37= correct?

Correct!

a complementary angle finds the other angle needed to "complete" it into a 90 degree angle, so x (37) and
90 - x (90 - 37) is the way
so Ly=53
Thank you for the response. I appreciate it.
