Hello,
The way to find the complement for a 11 degree angle is to subtract 11 from 90, and you get:
79!
A complement angle is basically an angle that equals up to 90 degrees, so if you ever need help with a question like this, remember this answer. Try finding a number that equals up to 90 degrees, so you can do
X + X = 90
Or
90-X= X
Hope this helps, have a good day. c;
