Question

In the given figure, $\sin \theta =\frac{BC}{AC}$.

• A. and
• B. False

Answer 1

The correct option is A

and

Observe that the side $AC$ is the hypotenuse as it is opposite to the right angle.

Sine of an angle is the ratio of the side opposite to it and the hypotenuse.
Side $BC$ is opposite to the angle $\theta$. So, $\sin \theta =\frac{BC}{AC}$.
