In a right triangle, if c = 12 and b = 10, what is the length of a in simplified form?

Answer 1

Eva Abramson

As the hypotenuse: #a = 15.62#

As an arm, #a = 6.633#

It is not indicated whether a is the hypotenuse or one of the arms of the right-angle.

If a is the hypotenuse.

#a^2 = 12^2 + 10^2 = 144 +100 = 244#

#a = sqrt244 = 15.62#

If a is not the hypotenuse:

#a^2 = 12^2 -10^2 = 144-100 =44#

#a = sqrt44 = 6.633#

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.
