how do you find out if a triangle with the side measurements of 84,13, & 85 is obtuse, acute, or right using the formula a2+b2=c2 (the twos are exponents)

a^2+b^2 = c^2 only true if it is a right triangle
so get out your calculator and see what 84*84 + 13*13 is
Not the answer you are looking for? Search for more explanations.
and then 85*85
i don't know what those little signs between the number means
a^2 means a to the second power (or a squared, or a times a (a*a)
oh okay when we do it we just do it a2. okay then hold on a sec
r u wanting me to do 84x84?
a2 is really not a good way to write it, because it really means a times 2
enough people do it here that I can guess what you mean, but it would be better to use the up-arrow.
okay i did it so it's a right triangle
a^2 + b^2 = c^2
means take the two shortest legs, square them, and add together. Compare this to the square of the longest leg.
Your calculator probably has a square button, but 84*84 gives the same answer
yes, looks good.
what would the equation be for an acute triangle
nvrmnd i figured it out
if c*c is too small then it is acute
