Question

1.If I know the lengths of two sides of a right triangle, how do I find the third?

Answer 1

is it right angled

Answer 2

you have to know an angle to find the third side

Answer 3

is there a step by step process to finding this?

Answer 4

if it is right triangle then
\[x^2+y^2=r^2\]

Answer 5

so if i have a triangle ABC. A=6 B=9 and we must find the length of C. i must multiply AxA and add that to the product BxB to find C squared. and to find C i must use the radical sign to undo C squared basically. correct me if im wrong? i think this is the pythagorean theorum

Answer 6

This is known as the Pythagorean Theorem.

Answer 7

\[a^2 + b^2 = c^2\]If a,b are two legs and c is the hypotenuse(longest side), then the above is true in a right triangle.

Answer 8

okay thank you!(:

Answer 9

I like examples, so I'd give one:
Find \(x\).

We know that 5 is the longest side because it is opposite 90.
Also, \(x\) and 3 are legs.
