Answer:
Answer <u>B</u>
Step-by-step explanation:
The formula for the area off a triangle is 1/2Bh
The base of the triangle is Z, and the height is W, so the formula is
Let X be a random sample representing the score of a student in the American Chemical Society Examination.
P(450 < x < 500) = P((450 - 500)/(90/sqrt(25)) < z < (500 - 500)/(90/sqrt(25))) = P(-2.778 < z < 0) = P(z < 0) - P(z < -2.778) = P(z < 0) - [1 - P(z < 2.778)] = P(z < 0) + P(z < 2.778) - 1 = 0.5 + 0.99727 - 1 = 0.49727 = 49.7%
The force of 10 pounds is made up of the horizontal components of the 8 and 5 pound forces
8 cos 30 + 5 cos 52 = 10
so your answer is 30 degrees

I know this answer because i got it right from the same source they got the question from.
