question 14(multiple choice worth 4 points)
(05.02 lc)
which equation is correct?
o tan x° = adjacent + opposite
o cos x° = opposite + adjacent
o tan x° = opposite + adjacent
o cos x° = adjacent + opposite

Explanation:

Step1: Recall trigonometric ratios

In a right - triangle, \(\tan\theta=\frac{\text{opposite}}{\text{adjacent}}\) and \(\cos\theta=\frac{\text{adjacent}}{\text{hypotenuse}}\).

Answer:

\(\tan x^{\circ}=\frac{\text{opposite}}{\text{adjacent}}\) (the third option: \(\tan x^{\circ}=\text{opposite}\div\text{adjacent}\))
