What made phillis wheatley literary  career  so  unusual?

Phillis Wheatley was an American poetess, the first black woman writer in the United States. She was captured and sent across the ocean in the Phillis. After some time, an auction took place, and the girl fell into the possession of Whitley's Boston family couple. She received her name from the name of the ship that delivered her to America. In addition to household tasks, the girl, under the guidance of Mary, the eighteen-year-old daughter of the owners, began to master English, learn Latin, read the Bible. The masters favored her poetic experiences. Despite recognition, American publishers refused to print Phillies’ collection of works. Fortunately, London friends were ready to help - Countess Huntingdon Selina Hastings, a Methodist and opponent of slavery who was friends with the late Whitefield, could contribute to the publication of the collection. John Wheatley, perhaps influenced by public opinion, granted Phyllis Wheatley freedom.

Explanation:

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°

i believe the correct answer is b.
