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
