Question

score: 2/10 current time: 95.9 find: sin a the figure is not drawn to scale answer $\frac{25}{65}$ $\frac{60}{25}$ $\frac{25}{60}$ $\frac{60}{65}$

Explanation:

Step1: Recall sine - ratio formula

The sine of an angle in a right - triangle is defined as $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$.

Step2: Identify opposite and hypotenuse for angle A

For angle $A$ in the given right - triangle, the side opposite to angle $A$ has length $60$ and the hypotenuse has length $65$.

Step3: Calculate $\sin A$

$\sin A=\frac{60}{65}$.

Answer:

$\frac{60}{65}$
