Find sin Please help

Explanation:

The side opposite angle A is BC = 8. This side is as far as you can get from angle A.

The hypotenuse is the longest side, and always opposite the 90 degree angle. The hypotenuse is AC = 10.

We can then say,

sin(angle) = opposite/hypotenuse

sin(A) = BC/AC

sin(A) = 8/10

sin(A) = (4*2)/(5*2)

sin(A) = 4/5 which points to choice B as our answer.

the answer is c
