1. ## Pyhagorean Theorem

I am getting the wrong answer in this problem
I must find sin, tan, sec, cos, cot, csc
The triangle - 2 on the adjacent and SQRT(3) is on the opposite and i must find the hypotenuse first
Using the theorem A^2+B^2=C^2 i get
(SQRT(3))^2+2^2=C^2
for 3+4=7
But the book says it is SQRT(21)

any suggestions

Thank you

2. Are you sure it's not the hypotenuse that has a length of 2?

3. I am sure

But the book says it is SQRT(21) ... if your side length info is correct, then the book answer is incorrect. It happens.
