Answer:
Step-by-step explanation:
cos theta is 5/13
so, adjacent=5 ,hypotenuse=13 and opposite=?
hypotenuse^2=adjacent^2+opposite^2
13^2=5^2+opposite^2
169-25=opposite^2
=opposite
12=opposite
sin theta=opposite/hypotenuse
=12/13
Using proportions, it is found that 5449.62 QR is equal to HKD 315920.
<h3>Proportions</h3>- This question is solved by <em>proportions</em>, using a rule of three.
- 2000 Qr are equal to 157960 NC. 1 HKD is equal to 13.62 NC, hence, how many QR are worth 13.62 NC?
Hence, the <em>rule of three</em> is:
2000 QR - 157960 NC
x QR - 13.62 NC
Applying cross multiplication:
Then:
- We have that 1 HKD is equals to 0.01725 QR. How many QR are equal to HKD 315920?
Then, the second <em>rule of three</em> is:
1 HKD - 0.01725 QR
315920 HKD - x QR
Applying <em>cross multiplication:</em>
5449.62 QR is equal to HKD 315920.
