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?

Draw a diagram. 20ft is the hypotenuse of the triangle. 12 ft is one of the legs.

Hint: use the pythagorean theorem.

$a^2+b^2=c^2$
$a=12, c=20$
