A radio station is going to construct a 5-foot tower on top of a building. The tower will be supported by three cables, each attached to the top and to points on the roof of the building that are 12-feet from the base of the tower. Find the total length of the three cables.

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form

The correct answer is b
