Answer: 4.25, 15, and 38.7°

Step-by-step explanation:

Use SOHCAHTOA

Sine is opposite over hypotenuse

Cosine is adjacent over hypotenuse

Tangent is opposite over adjacent

1.) tan(28) = x/8

8*tan(28) = x

x = 4.25

2.) tan(28) = 8/x

8/tan(28) = x

x = 15

3.) tan(x) = 4/5

x = arctan(4/5)

x = 38.7°
