Answer:
The choice third ; a=9 , c= 18
Step-by-step explanation:
![\sin(60) = \frac{9 \sqrt{3} }{c} \\ \\ c = 18](https://tex.z-dn.net/?f=%20%5Csin%2860%29%20%20%3D%20%20%5Cfrac%7B9%20%5Csqrt%7B3%7D%20%7D%7Bc%7D%20%5C%5C%20%20%5C%5C%20c%20%3D%2018%20)
![\tan(30) = \frac{a}{9 \sqrt{3} } \\ \\ a = 9](https://tex.z-dn.net/?f=%20%5Ctan%2830%29%20%20%3D%20%20%5Cfrac%7Ba%7D%7B9%20%5Csqrt%7B3%7D%20%7D%20%20%5C%5C%20%20%5C%5C%20a%20%3D%209)

Step-by-step explanation:
Future value with annuity:
The future value formula, for an annuity, is:
![FV = \frac{P((1+r)^{n} - 1)}{r}](https://tex.z-dn.net/?f=FV%20%3D%20%5Cfrac%7BP%28%281%2Br%29%5E%7Bn%7D%20-%201%29%7D%7Br%7D)
An annuity means that a number of payments happen during the period(an year, for example.
P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.
In this question:
1000 € each year, so ![P = 1000](https://tex.z-dn.net/?f=P%20%3D%201000)
Interest rate of 6%, so ![r = 0.06](https://tex.z-dn.net/?f=r%20%3D%200.06)
One application per year for 8 years, so ![n = 8](https://tex.z-dn.net/?f=n%20%3D%208)
Total amount:
![FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47](https://tex.z-dn.net/?f=FV%20%3D%20%5Cfrac%7B1000%28%281%2B0.06%29%5E%7B8%7D%20-%201%29%7D%7B0.06%7D%20%3D%209897.47)
There will be 9897.47€ in the account.
