Use the Pythagorean theorem to find x, in simplest radical form

Step-by-step explanation:

Pythagorean theorem is .

Which in this case:

'c' is hypotenuse. (hypotenuse = 20)

'a' and 'b' are the other sides. (a = x, b = 8)

Now we should just take square root from the both sides.

and the answer will be or , but a side of a triangle can not be a negative number! so the answer will be .

As you see is not the simplest radical.

We can write as .

And from the laws of radical we can write as .

Hello sorry can’t good luck tho

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
