Question

For a triangle with sides a, b and c, what is the range of the length of side c?
a = 418, b = 222, c =

Answer 1

I'm pretty sure that you're supposed to use Pythagorean Theorem on that problem. Pythagorean Theorem is: www.mathsisfun.com/pythagoras.html

Answer 2

yeah thats the thing idk what theorem i suppose to use idk if its that or the corollary

Answer 3

Using the side inequality of triangles which says that the sum of any two sides of a triangle is greater than the third side

a+b > c => 418 + 222 > c => 640 > c
So we can say that c < 640

Also, the difference of two sides of a triangle is less than the third side
so a - b < c => 418 - 222 < c => 196 < c

So 196 < c < 640

Answer 4

thanks you
