Check the picture below.
all we need to get the equation of the line is two points on it, in this case those would be (-3,2) and (1,1),
![\bf \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{2}=\stackrel{m}{-\cfrac{1}{4}}[x-\stackrel{x_1}{(-3)}]\implies y-2=-\cfrac{1}{4}(x+3) \\\\\\ y-2=-\cfrac{1}{4}x-\cfrac{3}{4}\implies y=-\cfrac{1}{4}x-\cfrac{3}{4}+2\implies y=-\cfrac{1}{4}x+\cfrac{5}{4}](https://tex.z-dn.net/?f=%5Cbf%20%5Cbegin%7Barray%7D%7B%7Cc%7Cll%7D%20%5Ccline%7B1-1%7D%20%5Ctextit%7Bpoint-slope%20form%7D%5C%5C%20%5Ccline%7B1-1%7D%20%5C%5C%20y-y_1%3Dm%28x-x_1%29%20%5C%5C%5C%5C%20%5Ccline%7B1-1%7D%20%5Cend%7Barray%7D%5Cimplies%20y-%5Cstackrel%7By_1%7D%7B2%7D%3D%5Cstackrel%7Bm%7D%7B-%5Ccfrac%7B1%7D%7B4%7D%7D%5Bx-%5Cstackrel%7Bx_1%7D%7B%28-3%29%7D%5D%5Cimplies%20y-2%3D-%5Ccfrac%7B1%7D%7B4%7D%28x%2B3%29%20%5C%5C%5C%5C%5C%5C%20y-2%3D-%5Ccfrac%7B1%7D%7B4%7Dx-%5Ccfrac%7B3%7D%7B4%7D%5Cimplies%20y%3D-%5Ccfrac%7B1%7D%7B4%7Dx-%5Ccfrac%7B3%7D%7B4%7D%2B2%5Cimplies%20y%3D-%5Ccfrac%7B1%7D%7B4%7Dx%2B%5Ccfrac%7B5%7D%7B4%7D)
Answer:
See below
Step-by-step explanation:
The three angles inside of the triangle sum to 180
11x + 4 + 3x + 78 = 180
14x +82 =180
x = 7
then B = 11x + 4 = 11(7) + 4 = 81 degrees
C = 3x = 21 degrees
2640/825=3.2
There is need 4 gallons to cover 2640 sq ft.
80% of the fourth gallon can be used for other purposes after painting.
