Answer:
If you need the answer as f by simplifying both sides of the equation and then isolating the variable, the answer would be:
![xf=\frac{3x^2}{5}-\frac{f(x)}{5}](https://tex.z-dn.net/?f=xf%3D%5Cfrac%7B3x%5E2%7D%7B5%7D-%5Cfrac%7Bf%28x%29%7D%7B5%7D)
Or, if you need to evaluate the function itself, the answer would be:
![f(x)=3x^2-5xf](https://tex.z-dn.net/?f=f%28x%29%3D3x%5E2-5xf)

Answer:
![sin(28) = \frac{y}{k} , cos(28) = \frac{x}{k} , tan(28) = \frac{y}{x}](https://tex.z-dn.net/?f=sin%2828%29%20%3D%20%5Cfrac%7By%7D%7Bk%7D%20%2C%20cos%2828%29%20%3D%20%5Cfrac%7Bx%7D%7Bk%7D%20%2C%20tan%2828%29%20%3D%20%5Cfrac%7By%7D%7Bx%7D)
Step-by-step explanation:
For this problem, k is the hypotenuse, x is the side adjacent to 28, and y is the side opposite 28.
I would remember SOH CAH TOA.
S - Sine
O - Opposite
H - Hypotenuse
For this, it shows that the sine of the angle is opposite over hypotenuse. Therefore, y/k.
C - Cosine
A - Adjacent
H - Hypotenuse
For this, it shows that the cosine of the angle is adjacent over hypotenuse. Therefore, x/k
T - Tangent
O - Opposite
A - Adjacent
For this, it shows that the tangent of the angle is opposite over adjacent. Therefore, y/x
