Answer:

  • x = 6.99 ft
  • y = 5.66 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA can remind you of the relevant relationships. The given side is the hypotenuse. x is the side opposite the given angle.

  Sin = Opposite/Hypotenuse

  sin(51°) = x/(9 ft)

  x = (9 ft)sin(51°)

  x ≈ 6.99 ft

__

  Cos = Adjacent/Hypotenuse

  cos(51°) = y/(9 ft)

  y = (9 ft)cos(51°)

  y ≈ 5.66 ft
