Question

A 3m ladder stands on horizontal ground and reaches 2.8 m up a vertical wall. how far is the foot of the ladder from the base of the wall? round your answer to the nearest hundredth.

Answer 1

1.08 m. is the answer because you would use the pythagorean theorem to solve it.  
2.8^2+b^2=3^2
7.84+b^2=9
b^2=9-7.84
square root of b^2=square root of 1.16
b=1.08
