Answer:
y=31.04668635
Rounded to 1dp would be 31.0
So Y=31.0cm
Step-by-step explanation:
Hypotenuse : Opposite the right angle.
Opposite : Opposite the angle.
Adjacent : the only side left.
Soh Cah Toa (trigonometry formula)
You don't need hypotenuse, so that's irrelevant.
You have opposite and adjacent, O and A, which is tan.
You need to rearrange the formula.
Length ×Tan(Angle) =Opposite.
37×Tan(40)=31.04668635cm
