Final answer:
The complement of angle T is 100 - 5x degrees.
Step-by-step explanation:
The complement of an angle is the angle that, when added to the given angle, results in a sum of 90 degrees.
In this case, the given angle is T = 5x - 10. To find the complement, we need to set up the equation: T + complement = 90 degrees.
Solving for the complement, we have: complement = 90 - T = 90 - (5x - 10) = 100 - 5x.
Therefore, the complement of angle T is 100 - 5x degrees.
