Answer:
51.3
Step-by-step explanation:
Tan(y) like all Tan Trig functions, is defined as the side opposite divided by the side adjacent.
The side adjacent is part of the reference angle.
The side opposite is not connected to the reference angle at all.
Side Opposite = 10
Side Adjacent = 8
Tan(y) = 10/8
Tan(y) = 1.25
y = Tan-1(1.25)
y = 51.34
y = 51.3
