to get the equation of any straight line, we simply need two points off of it, so let's use the points in the picture below.
now, if we use the last point from the table, namely (x , 17), we can see that x = x and y = 17, so let's plug those in the equation
![(17)-5=2(x-1)\implies 12=2x-2\implies 14=2x\implies \cfrac{14}{2}=x\implies 7=x \\\\[-0.35em] ~\dotfill\\\\ ~\hfill (7~~,~~17)~\hfill](https://tex.z-dn.net/?f=%2817%29-5%3D2%28x-1%29%5Cimplies%2012%3D2x-2%5Cimplies%2014%3D2x%5Cimplies%20%5Ccfrac%7B14%7D%7B2%7D%3Dx%5Cimplies%207%3Dx%20%5C%5C%5C%5C%5B-0.35em%5D%20~%5Cdotfill%5C%5C%5C%5C%20~%5Chfill%20%287~~%2C~~17%29~%5Chfill)
standard form for a linear equation means
• all coefficients must be integers, no fractions
• only the constant on the right-hand-side
• all variables on the left-hand-side, sorted
• "x" must not have a negative coefficient
2x + y = -9.
Answer:
Step-by-step explanation:
<em>Note all arguments of trigonometric functions are in degrees.</em>
<em />
Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).
Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.
