there is a picture of an angle whose sine is \(\frac{5}{6}\) all that is missing is the third side, which you find via pythagoras once you have all three sides, you can find any ratio that you like
cotangent will be "adjacent over opposite"
so i just times the 5 again and o the same to the 6 to get what it equals?
?

would it be 25 & 36?
no

\[a^2+5^2=6^2\] by pythagoras so \[a^2=6^2-5^2=36-25=11\] making \(a=\sqrt{11}\)
I meant to say that but it came out wrong, so now would I have to do \[\sqrt{11}/5\]
