Mathematics: For a crane to lift the beam shown to the right, the beam and the two support cables must form an isosceles triangle with height h. if the distance between the cables along the beam is 18 ft and the height h is 8 ft, what is the total length of the two cables?

The total length of the two cables is $2\sqrt{145}\ units$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

In the right triangle ABD

Applying the Pythagoras Theorem

$AB^{2}=BD^{2}+AD^{2}$

substitute the given values

$AB^{2}=9^{2}+8^{2}$

$AB^{2}=145$

$AB=\sqrt{145}\ units$

Remember that

AB=AC ----> because ABC is an isosceles triangle

The total length of the two cables is equal to

$AB+AC=2AB=2\sqrt{145}\ units$

Step-by-step explanation:

(12x4)/2=6

11x3=33

11x4=44

11x5=55

hopefully this helps :)
