A boat drops an anchor to the bottom of a lake. The anchor is pulled back under the boat at an angle of 13 degrees with the boat. The lake is 25 feet deep. To the nearest hundredth of a foot, what is the length of the anchor rope?
I got 25/sin13
I got 25/cos13
The 13 degrees is between the anchor rope and the verticial depth.
So you have the hypotenuse and the adjacent sides.
