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!!
