Maybe try to round the percents to the nearest hundret to the answer
Answer: There is an image explaining it.
3rd angle is 100
All Angles of a triangle add together will equal 180
20+60=80
180-80=100
A trigonometry rule is the range of Tangent is all real numbers
The answer would be y = tanx and y=cotx
