Akite on a 160-foot string is caught on a pole. when the full length of the string is stretched in a straight line to the ground, it touches the ground a distance of 50 feet from the bottom of the pole. the string forms an angle of ° with the ground when it is stretched like this.

We are asked to solve for the angle created between the distance of the string when stretched towards the bottom of the pole and the distance of the string from the top of the pole. The solution is shown below:
50 feet = from the pole stretched straight on the ground towards the bottom of the pool
160 feet = for the hypotenuse
We can use and apply SOH CAH TOA to solve this problem such as:
cos X = 50 / 160
x = 71.8°

The answer is the letter '"C" or the third item in the choices which is 72°. 

72 is the answer this is probly on odyssey ware but yes it is correct becuz im pretty sure it is
