Question

which equation is correct?
cos x° = adjacent + hypotenuse
tan x° = hypotenuse + adjacent
cts x° = hypotenuse + adjacent
tan x° = adjacent + hypotenuse

Explanation:

Step1: Recall trigonometric - ratio definitions

In a right - triangle, $\cos x^{\circ}=\frac{\text{adjacent}}{\text{hypotenuse}}$, $\tan x^{\circ}=\frac{\text{opposite}}{\text{adjacent}}$, and $\cot x^{\circ}=\frac{\text{adjacent}}{\text{opposite}}$.

Answer:

None of the given options are correct.
