Answer:
x = 17.96829419
rounded to 1dp would be
x = 18.0cm
Explanation:
Hypotenuse : Opposite the right angle.
Opposite : Opposite the other angle
Adjacent : Last side left.
We don't need the hypotenuse so we can get rid of that.
We have adjacent (a) and opposite (o) for trigonometry.
Soh Cah Toa
Toa has o and a so we're going to use tan.
Length × Tan (Angle)
8 × tan (66) =17.96829419
