Fittoniya [83]

Answer:

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

so

The total length of​ the two cables is equal to

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