Question 949814
Each cable is the hypotenuse of a right triangle with one leg 6yds(4 yd from top of 10 yd pole) and the other leg 8 yd (distance from base of pole)
c=length of cable; b=distance from base of pole; a=distance up pole
{{{c^2=a^2+b^2}}}
{{{c^2=(6 yds)^2+(8 yds)^2}}}
{{{c^2=(36 sq yds+64 sq yds)}}}
{{{c^2=100 sq yds}}} find square root of each side.
{{{c=10 yds}}}
ANSWER: The length of one cable is 10 yards, and since there are three cables,a total of 30 yards of cable will be needed.
