Answer: Option B.

Step-by-step explanation:

You neeed to use the trigonometric identity:

sin\alpha=\frac{opposite}{hypotenuse}

As you need to find sin∠A, you can identify in the right triangle that:

opposite=8\\hypotenuse=10\\\alpha=A

 Finally, substitute the angle, the lenght of the opposite side and the lenght of the hypotenuse into sin\alpha=\frac{opposite}{hypotenuse} to find sin∠A. Then, you get:

sinA=\frac{8}{10}

Reducing the fraction:

sinA=\frac{4}{5}

This is the option B.

A weed called the raindrop vine is known for growing at a very fast rate.
Vinvika [58]

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.
