HOPE THIS HELPS!!!!!!! ;-)
18/230 = (approximately) 0.07826.
Multiply by 100 to change the decimal to a percent.
<span>The canyon starts at an elevation of (-14.5). After each year, the elevation drops by (-1.5). The equation that could be written for this, then, would be (-14.5 - 1.5x = -31). First, we could add 14.5 to both sides of the equation to isolate the unknown. This would leave -1.5x = -16.5. Next, we can remove the negative signs so both sides of the equation are positive and easier to work with. This leaves 1.5x = 16.5. Finally, dividing both sides by 1.5 gives us "x = 11", which means that after 11 years, the canyon floor will be at -31 feet.</span>
A thousand ways you could solve this, but generally need to understand 3 concepts to do so
1. interior angles of triangle add up to 180 degrees
2. law of sines
3. law of cosines
my personal suggestion
determine what angle A is, then use law of sines in order to determine side c
