Question

Need help with trigonometry

Answer 1

Explanation:

Let us first find the hypotenuses of the right triangle.

`c=√(12^2+9^2) =√(225) = 15`

`sin(theta) = 12/15 = 4/5\\cos(theta) = 9/15 = 3/5\\tan(theta) = 12/9 = 4/3\\csc(theta) = sin(theta)^(-1) = 5/4\\sec(theta) = cos(theta)^(-1) = 5/3\\cot(theta) = tan(theta)^(-1) = 3/4`
