Question

What is the missing length of the side of this triangle?

Answer 1

5

Answer 2

using the Pythagorean theory to get the formula leg^2+leg^2=Hypotenuse^2
(Or A^2+B^2=C^2)
You get \[4^{2}+3^{2}=25
25=c^2 So you just take the square root of 25 to get 5 for the missing side
Just remember that if 3 were the other line the proper formula would be 4^2+b^2=3^2

Answer 3

you must use a^2+b^2=c^2
whe you do the algebra you get
\[\sqrt{9+16}\] this =\[\sqrt{25}\] which is known to be 5
