Question

Can someone help find what C is?

Answer 1

Hello there!

Here, we want to use the Pythagorean Theorem:
`a^(2) + b^(2) = c^(2)`.

For problem number 7, we plug 6 and 8 in for a and b. Like this:

`6^(2) + 8^(2) = c^(2)`

Now we solve.
`6^(2)` is 36.
`8^(2)` is 64.

64 + 36 = 100

Then, we take the square root of 100 to get c.

`√(100) = 10`

(There's something special about this triangle. If you want I'll tell you about it in the comments.)

For problem number 8, we do the same exact thing.

`4^(2) + 12^(2) = c^(2)`

`4^(2) = 16` and
`12^(2) = 144`

`144 + 16 = 160`

`√(160) = 8√(10)`

I hope this helps!!
