For the first one we will use the Law of Sines. First off, though, we need to find angle C's measure. By the Triangle Angle-Sum Theorem, the angles of a triangle all add up to equal 180. Therefore, angle C is 180-15-20 which is 145 degrees. Now we will set up the Law of Sines ratios. 
. Solving for BC, we have 
and on our calculators we find that BC is 4.5, last choice above. For the second one, the sin ratio is the side opposite the reference angle over the hypotenuse. The cos ratio is the side adjacent to the reference angle over the hypotenuse. The side opposite angle R is r, and the hypotenuse is q, so the sin R = r/q. For the cos P, the side adjacent to angle P is r, and the hypotenuse is q, so the cos P = r/q. Obviously, those 2 ratios are the same, so your choice is the very first one given.

Answer:
The answer is No.
Step-by-step explanation:
Zeituni's standard deduction on her federal income tax return is $5700.
she paid $4670 in state taxes and $1180 in mortgage interest last year, totaling to :
So, no, she should not use her standard deduction because it is less than the deduction she will get from itemizing.

Well, the place is charging him 115/hr
and he's booked it for 6hrs
how much is going to be his cost? well
now, there will be 14 teams playing, so... if we divide 690 evenly among the 14 teams, that means each team will need to pay 690/14 about 49.28571 or 49 bucks and 29 cents about
now, if each team pays that much, they'll cover 690, so Dylan has his cost covered, however, for a profit, a profit is surplus, so, in order to make surplus income, or profit, he'll need to charge "more than" 49.29
or he needs to charge "x", whilst x > 49.29
