The picture below shows a right triangle shaped charging stand for a gaming system.Which expression shows the length of side AB? 8 tan 60° 8 cosec 60° 8/cos60 8/sin60

since cos(60 degrees) = 8/y, then y = 8/cos(60 degrees) where y is the length of AB.

btw, this is a 30-60-90 triangle so the shortest side which is opposite the 30 degree angle is half the length of the hypotenuse. Therefore AB = 16

AB = 8/cos60
