Question

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

• 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, $sin\theta$ = $\frac{BC}{AC}$.
