Final answer:
The complement of the angle (10+y) is 80 - y.
Step-by-step explanation:
The complement of an angle is defined as the angle that, when added to the given angle, gives a sum of 90 degrees.
To find the complement of the angle (10+y), we subtract the given angle from 90 degrees:
Complement of (10+y) = 90 - (10+y)
Simplifying the expression, we get:
Complement of (10+y) = 80 - y
