Question

1. if a = 16 and b= 12, find c

Answer 1

Answer:

20

Step-by-step explanation:

The pythagorean theorem states that

$a^2+b^2=c^2$

So $16^2 + 12^2 = c^2\\256+144 = c^2\\400 = c^2$

You would then do

$400 = c^2\\\sqrt{400} = c$

Because a square root is the opposite of a square.

$\sqrt{400} = 20$

because 20 * 20 = 400
