Answer:
243.911, or rounding to the nearest unit, 244.
Step-by-step explanation:
For this, you need to know a concept in Trigonometry called "Law of Sines". This states that the ratio of any side of a triangle to the sine of the angle opposite is equal for all cases in that triangle.
Knowing this:
![\frac{200}{ \sin(48) } = \frac{x}{ \sin(65) } \\ x \sin(48) = 200 \sin(65) \\ x = \frac{200 \sin(65) }{ \sin(48) } \\ x = 243.911](https://tex.z-dn.net/?f=%20%5Cfrac%7B200%7D%7B%20%5Csin%2848%29%20%7D%20%20%3D%20%20%5Cfrac%7Bx%7D%7B%20%5Csin%2865%29%20%7D%20%20%5C%5C%20x%20%5Csin%2848%29%20%20%3D%20200%20%5Csin%2865%29%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B200%20%5Csin%2865%29%20%7D%7B%20%5Csin%2848%29%20%7D%20%20%5C%5C%20x%20%3D%20243.911)
The answer is f(x)=(x-2)/7
to find the inverse of a function, swap x and y and then find y. hope this helps!
<u>b = 1/6 r w</u>
Multiply each side by 6 : 6b = r w
Divide each side by 'w' : <em>6b / w = r
</em>
