Question

Is this correct?

Answer 1

question: How far up a wall will an 11 meter ladder reach, if the foot of the ladder must be 4 meters from the base of the wall? Round to the nearest hundredth.


my answer:
4^2 + b^2 = 11^2

16 + b^2 = 121

16 + b^2 - 16 = 121 - 16

b^2 = 105

√b^2 = √105

b = √105

b ≈ 10.25
The ladder must go approximately 10.25 meters up the wall.
