Question

How do I find the missing lengths of a right triangle if I only know the hypotenuse which is 20

Answer 1

a^2 + b^2 =20^2
let b=20-a
so
a^2 + (20-a)^2= 400

Answer 2

then u solve for a and b=20-a

Answer 3

So it could be like 5 + 15 = 20 - 5?

Answer 4

no just use the equation on top to solve for variable a first

Answer 5

actually wait....sorry i dont think b=20-a

Answer 6

Oh ok I get it thanks!

Answer 7
