Question

a 10ft tent pole has a support rope that extends from the top of the pole to the ground. The rope and the ground form 30 degree angle. How long is the rope, rounded to the tenth place

Answer 1

For this question, we will use:
sin(∅) = perpendicular / hypotenuse

The perpendicular is 10 ft, and the hypotenuse is the length of the rope
hypotenuse = perpendicular / sin(∅)
hypotenuse = 10 / sin(30)
hypotenuse = 20 ft

The length of the rope is 20 feet.
