Instructions Solve the following problem and choose the best answer.
Question
P= (6, 7, 11, 12, 15)
Q = {4, 7, 12, 15, 20)
S=(3, 4, 11, 12, 16)
Given sets P Q and S above, which of the following sels represents Sn(PUR) (the intersection of S
with the union of sets Pand Q)?
(3, 4, 7, 11, 12, 15, 16)
14, 6, 7, 11, 12, 15, 20)
14,7, 12, 15)
14, 11, 12)

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
