Question

in the right triangle , find the length of the side not given. give an exact answer and an approximation to three decimal places. a-8, h=8
what i did is 8^2 + 8^2 = 128 for c^2
which is 8 √2 but i don't know how to find the approximation

Answer 1

\[c ^{2}= 128\]

Answer 2

\[c=\sqrt{128}=\sqrt{64(2)}=8\sqrt{2}\]

Answer 3

That is the exact answer. Now find the square root of 2 using your calculator, multiply by 8 and round to 3 decimal places and that will be the approximation
