Answer:
7. Cos Z
=> Cos theta = Base /Hypotenuse
=> Cos Z = 30/50 => 3/5
★ So, Option B) 3/5 is a correct answer.

8. Cos X
=> Cos theta = Base/Hypotenuse
=> Cos X = 12/37
★ So, option D) 12/37 is a correct answer.

9. Sin Z
=> Sin theta = Perpendicular/Hypotenuse.
Sin Z = 16/20 => 4/5
★ So, option C) 4/5 is a correct answer

10. Sin Z
=> Sin theta = Perpendicular/Hypotenuse
Sin Z = 48/50 => 24/25
★ So, option A)24/25 is correct answer
