Which statement would most likely have been made by an American worker in the early 1800s? A. I think I'll get a job in a factory.

B. I used to work, but now all the big businesses are closing.

C. The only opportunity for me is in farming.

D. There are more jobs for me in the West.

A, I think I'll get a job in a factory.

angle a = 40.6°

step-by-step explanation:

for any right angle triangle we know the pythagoras theorem reveals

hypotenuse² = height²+base²

by this formula we will calculate the length of hypotenuse

h² = 6²+7²

⇒ h =√36+49 = √85 = 9.22

now from the given triangle sin a = height/ hypotenuse

                                                sin a = 6/9.22 = 0.651

therefore

so angle a = 40.6°
