The towrope pulling a parasailor is 70m long. They estimate that the angle between the towrope and the water is about 30°. Find the height of the parasailor above the water, to the nearest 10m.

Answer 1

sin 30 = h/70

but we all know sin 30 = 1/2

so 35

Answer 2

so 70 would be the hypotenuse of your right-angled triangle and you want the height, which is opposite your angle of 30°
According to SOHCAHTOA
sin30° = h/70
h = 70sin°
= ....

Answer 3

Thank you!!
