Answer:
x = 55.6
Step-by-step explanation:
Recall the 3 main trig functions
Sin = opposite / hypotenuse
Cos = adjacent / hypotenuse
Tan = opposite / adjacent
Note that hypotenuse = longest side length
We want to find angle "x".
We are given its opposite side length ( 19 ) as well as the adjacent side length
When dealing with the opposite and adjacent we use tan
Tan = Opp / Adj
Opp = 19 and Adj = 13
Tan(x) = 19/13
* take the inverse tan of both sides *
x = 55.6
5x - 2y = 10
Isolating y:
-2y = 10 - 5x
y = (10 - 5x)/(-2)
y = 10/(-2) + (-5x)/(-2)
y = -5 + 5/2x
This equation has the slope-intercept form with a slope of 5/2 and a y-intercept of -5
So you have 328 lemons at first right?
And you gave 246 to your neighbor right?
That means you have to takeaway 246 from 328 right?
So 328-246 is 82 ok?
So you have 82 lemons left
