(6,1)&(5,4) (7,-3)&(4,-8) (-8,0)&(1,5) Basically, you are to find the line that passes through 2 points. Equation: y2-y1=m(x2-x1) • x1: 6, x2: 5, y1: 1, y2: 4 (4-1)/(5-6)=m m=3/-1 m=-3 Hence, m= -3x10^0
Step-by-step explanation: I use the Law of Cosines to find one of the angles of the triangle. Then use the formula for the area of the triangle: A = (1/2)absinC.
C= 92.856 degree
Area = (1/2)(112)(148)sin(92.856°) = 8277.7 ft^2
To find the price just need to take 8277.7 time 20 = 165554
