Question

A ladder that is 14 feet long is placed against a building. The bottom of the ladder is 6 feet from the base of the building.

In feet, how high up the side of the building is the top of the ladder? Round to the nearest tenth of a foot.

Answer 1

12.7

Explanation:

got it right with that answer on edge

Answer 2

12.7ft

Explanation:

this involves the Pythagoras theorem: base² x height² = hypotenuse²

b² x h² = hyp²

6² x h² = 14²

36 x h² = 196

h² = 196 - 36

h² = 160

h = square root of 160

h = 12.65 - to the nearest tenth

= 12.7ft
