A square canopy is supported on 4 corners by poles. Each pole is supported by 3 cables, each is attached to the top of the 12 foot pole and 5 feet away from the base. Find the length needed for the all of the cables.
A. 144 ft
B. 156 ft
C. 51 ft
D.204 ft
+128657 Yeah..I did......the post and the distance the cable is anchored from the post represent the two legs....so we have:
12^2 + 5^2 = h^2 where h is the hypotenuse (the cable length) ...so...
144 + 25 = h^2
169 = h^2 take the square root of both sides
13 = h = the cable length in feet
Does that make sense???
+128657 Each cable forms a right triangle with the post..... the post = 12 feet, the distance the cable is anchored from the post = 5 feet... and the cable length itself = the hypotenuse = √[12^2 + 5^2] = √169 = 13 feet
And we have 3 of these on each post and 4 posts in total....so...the total length = (13)(3)(4) = (13)(12) = 156 ft
