My sister needs help with this assignment so she can receive an “A” please help us with the whole assessment ):

Hi, you should tell your sister that she will not learn what she needs to learn without doing this assignment on her own. This is not very difficult and is crucial to learn for several math courses in her future. Good luck with it! P.S. You cannot get an A in a class without actually knowing the stuff you are supposed to learn!

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
