Answer:
−0.965925826289068
Step-by-step explanation:
sin 255 = −0.965925826289068
The options you gave are extremely confusing, but if you round 7.9 it is 8, and if you round $3.89 it is $4. Therefore, the best estimate would be 8•$4, or $32
C-53.62 times however many she bought.
so c-(53.62x)
because you are taking how much money she spent and subracting it from how much she had
Answer:
x=24
Step-by-step explanation:
Answer: second option.
Step-by-step explanation:
You must apply ![sin\alpha=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=sin%5Calpha%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
Then, given the right triangle and the angle D, the opposite side and the hypotenuse of the triangle are the following:
![opposite=20\\hypotenuse=25](https://tex.z-dn.net/?f=opposite%3D20%5C%5Chypotenuse%3D25)
Therefore, when you substitute values, you have:
![sinD=\frac{20}{25}](https://tex.z-dn.net/?f=sinD%3D%5Cfrac%7B20%7D%7B25%7D)
Reduce the fraction, then you obtain:
![sinD=\frac{4}{5}](https://tex.z-dn.net/?f=sinD%3D%5Cfrac%7B4%7D%7B5%7D)
