Answer:
SinA = 40/50
Step-by-step explanation:
I think it's just asking if you understand the trig ratios. You aren't really solving for anything.
SinA is 40 over 50 because 40 is opposite of <A and 50 is the hypotenuse.
Then, use the trig ratios to figure out the other problems.

Answer:
30
Step-by-step explanation:
12 is 40% of the total number of cards.
12 = 0.4x, where x is total number of cards
/0.4 /0.4
30 = x
30 cards
Answer:s=10.50 and p=27
Step-by-step explanation:
Answer:
Adult=58
Step-by-step explanation:
c=child, a=adult
6.4c+9.7a=1145 equation 1
c+a=149 equation 2
a=149-c modified equation 2 to isolate a
6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2
6.4c+1445.3-9.7c=1145
-3.3c=-300.3
c=91
solve for a
c+a=149
91+a=149
a=58
Check answer:
6.4c+9.7a=1145
6.4(91)+9.7(58)=1145
582.40+562.60=1145
1145=1145
