Question

score: 9/10 current time: 175.8 find: sin a the figure is not drawn to scale answer $\frac{76}{95}$ $\frac{57}{76}$ $\frac{76}{57}$ $\frac{57}{95}$

Explanation:

Step1: Recall sine - definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$.

Step2: Identify opposite and hypotenuse for angle A

For angle $A$ in the given right - triangle, the side opposite to angle $A$ has length $76$ and the hypotenuse has length $95$.

Step3: Calculate $\sin A$

$\sin A=\frac{76}{95}$.

Answer:

$\frac{76}{95}$
