The complement of an acute angle A in degrees is 90 - A. So if the complement is 25 degrees, the angle would be 90 - 25 = 65 degrees.
If you have an angle and want to know its complement, you subtract it from 90 degrees. What angle, when subtracted from 90 degrees, gives the same value?
90 - x = x
The supplement of x is the angle that you add to x to make 180 degrees. In other words, 180 - x = the supplement of x.
So you divide 12.00 by 0.75 and you get 16 which is the number of cookies he sold.
I did part of it but the rest idk sorry
