Draw a horizontal line to signify the starting point. From this line draw an angle of 20 degrees from it.Quote:

You should now have a right-angled triangle to work with. We know that the hypotenuse is 500m and the angle is 20 degrees. To find the height label the vertical line h and note this opposite the 20degree angle.
We now have an angle and the hypotenuse while needing to find the opposite. Can you recall a trig ratio to use in this situation
Sin= opp. side/ hypotenuse?
Almost correct.
It's actually
.
So substituting in your values gives
.
Solve for.
thx i get it :D thx to all of you...
