Answer:
95
Step-by-step explanation:
angle K and angle U are supplementary meaning when they are added they equal 180. In order to find angle K, you have to subtract 180-85 and it will get you 95.
If two parallel lines are cut by a transversal, the corresponding angles are congruent.
If the hat is 15% off, then he will pay = 100 - 15 = 85%
