Question

What is the length of side c to the nearest tenth of a foot?

Answer 1

Use the Pythagorean theorem
\[a^2+b^2=c^2\]

Answer 2

\[400^2+900^2=c^2\]
To simplify things, we're going to divide by 100 to get this
\[4^2+9^2=c^2\]
\[16+81=c^2\]
\[97=c^2\]
\[c=\sqrt{97}\]
\[c \approx 9.849\]
Since we divided this by 100, we have to multiply by 100, so the answer would be
\[984.9 \] feet

Answer 3

Hope this helps buddy!

Answer 4

@steve816 Thank you! Now what if I had to find angle a with the same information?

Answer 5

Then you would use a little bit of trigonometry!

Answer 6

@steve816 Is angle a what is known as theta if I'm not mistaken?
