Math, microeconomics or criminal justice
84 tall, 69 angle
height = opposite side of a right triangle
answer to the problem is the hypotenuse of the right triangle
sin69 = opposite side over hypotenuse= o/h
h= o/(o/h) = 84/sin69
h= 84csc69
h = about 89,98 = about 90 feet = length of the support cable
