from the top of a tower, the angle of depression to a stake on the ground is 60 degrees. the top of the tower is 80 feet above ground. how far is the stake from the foot of the tower.

identify consequences of international trade.

identify consequences of international trade.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
