Question

A 10-foot ladder leans against a wall with its foot braced 3 feet from wall’s base. How far up the wall does the ladder reach? Show your work. Round answer to the nearest hundredths. IF THE PICTURE IS NOT UP PLEASE RELOAD THE PAGE THANK YOU!

Answer 1

Wall height^2 = 10^2 - 3^2
wall height^2 = 91
wall height = 9.5393920142 =
9.54 feet (rounded)

Answer 2

Here, Just apply the Pythagoras theorem, 
h² = p² + b²
10² = p² + 3²
100 - 9 = p²
p = √91

In short, Your Answer would be √91 or 9.53 Ft

Hope this helps!
