    solid geometry

    I need an urgent help with this problem, hope that you can explain to me how.
    Thank you for your time. God bless.

    From a point 55m up from the ground on a vertical antenna pole, three guy cables are stretched to anchors which are located at the vertices of an equilateral triangle 20m on a side. Find the length of each cable if the foot of the pole is equidistant from the anchors.

    Again you do not show any work ...anyway..
    Hint: since the pole is equidistant from the anchors...and the three anchors form an equilateral triangle..it means that the pole is located at the center of the circumcircle of the trialgle.This center of cource coincides with the intersection point of the 3 MEDIANS....( The barycenter ) because the triangle is equilateral.does this mean anything to you? if yes the rest is easy...try...
