Question

What is the trigonometric ratio that connects the opposite side and the hypotenuse?

• A. $cos\theta$
• B. $tan\theta$
• C. $sin\theta$
• D. $sec\theta$

Answer 1

The correct option is C $sin\theta$

Trigonometric ratio sine is the ratio of the length of the opposite side to the length of the hypotenuse

\( sin~\theta = \frac{\text{opposite side}}{\text{hypotenuse}} \)

Hence, the ratio that relates the opposite side and the hypotenuse is $sin\theta$
