?A man on the top of a building wants to have a guy wire extend to a point on the ground 10 ft from the building. To the nearest foot, how long will the wire have to be if the building is 35 ft tall?

Solution

Apply pythogoras theorem to find the length of wire

length of wire^2 = height of building^2 + horizontal distance from building^2

= 35^2 +10^2

= 1325

length of wire = sqrt(1335) = 36.40 feet
