Question

a ladder that is 12 feet long is placed against a wall. The bottom of the ladder is 4 feet from the wall. to the nearest foot, how far up the wall does the ladder reach? a) label the known lengths. label the unknown length x. b) use the pythagorean theorem to write an equation you can use to find the value of x. c) solve the equation in part (b) for x. d) round your answer from part (c) to the nearest whole number.

Answer 1

\[\sqrt{12^2-4^2}=11.3137 \]

Answer 2

11.3137 = 11 rounded.

Answer 3

This is the working out. Please try to attempt the problem yourself as well :) (Teachers DO deduct marks if you show no workings out)

Good luck!
