109 is on a straight line with an interior angle of a triangle, so 180 - 109 = 71 degrees.
Add two known interior angles (71 + 49) together and you get 120 degrees.
Subtract 120 from 180 (since 180 is the sum of all three interior angles of a triangle) and you get 60 degrees.
Answer: ∠ULE is 60 degrees
