Question

score: 2/10 current time: 60.1 find: sin a the figure is not drawn to scale answer 28/45 45/53 28/53 45/28

Explanation:

Step1: Recall sine - ratio definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For angle $A$, the side opposite to angle $A$ is $45$ and the hypotenuse is $53$.

Step2: Calculate $\sin A$

$\sin A=\frac{45}{53}$

Answer:

$\frac{45}{53}$
