What is the length of the long leg if the short leg is 3 and the hypotenuse is 16

leg^2 + leg^2 = hypotenuse^2

3^2 + x^2 = 6^2

6^2= 36

3^2 = 9

36 - 9 = 27

sqrt of 27 = 5.196

Rounded = 5.2

Hope this helps

b= 15.72 (rounded) or √247

Step-by-step explanation:

a^2+b^2 = c^2

--> first set up a equation following the Pythagorean theorem

3^2 + b^2 = 16^2

--> simplify

b= 15.72 (rounded) or √247

hope this helped :)
