I used a tutor for this and the answer I was given is 17.5. Which is incorrect. I am trying to understand how to solve.​

So you need to decide if you are using cos,sin or tan

You use soh cah toa for this

You label the sides

Hypotenuse - which is the side opposite the right angle

Opposite- which is the side opposite the angle given

Adjacent - the left over side

In this case the opposite doesn’t have any values so we are going to cross it out

We are using CAH

Put this into your calculator : Cos(73)x6

Cos(73)x6 = 1.754230228

The answer is 1.8 to 1 decimal place
