Sin θ =
If θ = 51° ; opp = QR ; hyp = 17 cm
Then sin 51° =
⇒ QR = (sin 51°) (17 cm)
= 13.21 cm
∴ the answer is OPTION C
Use algebra.......such as remember PEMDAS do that :)

Answer:
16 credits
Step-by-step explanation:
Divide $1218 by 12 to find out how much 1 credit costs. It's $101.50
Because he paid $1624 total for spring, you'll divide that by $101.50 because it's per credit.
1624/101.5 = 16 credits.
hope this is good enough
Answer: Smaller number = 6
Larger number = 20
Step-by-step explanation:
Let the smaller number be x.
Let the larger number be y.
Three times a larger number is 30 more than 5 times a smaller number. This will be:
3 × y = (5 × x) + 30
3y = 5x + 30 ...... i
The sum of the larger number and 5 times the smaller number is 50. This will be:
y + 5x = 50 ...... ii
From equation ii
y + 5x = 50.
y = 50 - 5x ...... iii
Put the value of y = 50 - 5x into equation i
3y = 5x + 30
3(50 - 5x) = 5x + 30
150 - 15x = 5x + 30
150 - 30 = 5x + 15x
120 = 20x
x = 120/20
x = 6
The smaller number is 6
Note that y + 5x = 50
y + 5(6) = 50
y + 30 = 50
y = 50 - 30
y = 20
The bigger number is 20
