A flagpole has a height of 16 yards. It will be supported by three cables, each of which is attached to the flagpole at a point 4 yards below the top of the pole and attached to the ground at a point that is 9 yards from the base of the pole. Find the total number of yards of cable that will be required.
Accepted Solution
A:
Cables are forming 3 right angled triangles the pole being the shared height of them;
(height) b= 12yd (base) a= 9yd (hypotenuse) c= ? Need to find the long side (hypotenuse);
a^2 + b^2 = c^2
12^2 + 9^2 = 225 Take square root of 225 = 15 Then you have;
