how do i determine whether 27, 120, 123 are the measures of the sides of a right angle....and after that then state whether they form a Pythagorean triple?????......PLEASE HELP:)

Question

zarkon · Answer

is $27^2+120^2=123^2$?

zarkon · Answer

also I assume you mean  the sides of a right triangle

anonymous · Answer

yeah

anonymous · Answer

use the Pythagorean Theorem, like @Zarkon did

anonymous · Answer

o okay thank you both

anonymous · Answer

$$a^2 + b^2 = c^2$$

where "c" is the longest side (aka the hypotenuse) and "a" & "b" are the other side lengths (aka the legs)

anonymous · Answer

So: 
 27, 120, 123
$$27^2 + 120^2 = 123^2$$
$$729 + 14400 = 15129$$
$$15129 = 15129$$

THEREFORE, the side lengths given (27, 120, 123) can form a right triangle.
