Answer:
The measure of the unknown angle is 15°.
Step-by-step explanation:
Represent this angle by A.  Then the complement of A is 90° - A.
"Angle whose complement is five times its measure" would be expressed as 
90° - A = 5A
Solve this for A by adding A to both sides:
90° = 6A.  Then A = 90°/6, or 15°
