timed problem
score: 7/10 current time: 109.2
find: sin a
the figure is not drawn to scale
answer
55/48 48/73 48/55 55/73

Explanation:

Step1: Recall sine - ratio definition

In a right - triangle, $\sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}$. For angle $A$ in the given right - triangle, the side opposite to angle $A$ is $55$ and the hypotenuse is $73$.

Step2: Calculate $\sin A$

$\sin A=\frac{55}{73}$

Answer:

$\frac{55}{73}$
