Question

Find cos, csc, tan of angle in triangle? See image!

Answer 1

The other side can be obtained by Pythagorean's theorem
\(5^2+x^2=8^2\)
\(x^2=64-25\)
\(x^2=39\)
\(x=\sqrt{39}\)
Now you can just use SOH CAH TOA

Answer 2

Whats that?

Answer 3

SOH= sin =opposite/hypotenuse
CAH= cos = adjacent/hypotenuse
TOA = tan = opposite/adjacent
