A 20-ft ladder is leaning against a building. If the bottom of the ladder is 12ft from the base of the building how high does the ladder reach?

A= 20ft - 12ft

A = 8 ft

Seems too simple is this a trick question?

$\displaystyle a^2+b^2=c^2$

$\displaystyle a=12, c=20$ - Jun 26th 2008, 09:12 AMmasters
