Question

What is the missing length?
Help

Answer 1

5

Explanation:

using Pythagorean theorem:

`a^2+b^2=c^2`

a and b are sides

c is the hypotenuse

in this case we need a side:

`a^2+12^2=13^2\\a^2 + 144 = 169\\`

subtract 144 from 169

`a^2=25\\√(a) ^(2) = √(25)`

so a = 5

THE ANSWER IS 5 :)
