A right triangle has two sides that are each 12 feet long. To the nearest foot, what is the length of the third side?

Answer 1

17 feet

for right-angled triangles: #a^2 + b^2 = c^2#
if 2 sides are equal, then #a=b#
#2a^2=c^2#
#a=12#
#2a^2=2*12^2=2*144=288#
#c^2=288#
#c=sqrt(288)=16.9#
#16.9# is #17# to the nearest 1, so #16.9ft# is #17ft# to the nearest foot.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
