Answer:
area of triangle: 1.2975
area of circle: π ≈ 3.1416
Step-by-step explanation:
The side length (B) is used to compute the perimeter of the triangle. For the 3-sided triangle, the perimeter is ...
P = 3B = 3·1.73 = 5.19
The "height" (H) measured from the center of the circle to the middle of one side is called the "apothem" (a). The area of the triangle (A) is the product of half that and the perimeter:
A = (1/2)aP = (1/2)·0.5·5.19 = 1.2975 . . . . . . square units

Find Slope
--------------------------------------------------
y = -1/3 x + 4
Slope = -1/3
Slope of the parallel line = -1/3
--------------------------------------------------
Insert slope into y = mx + c
--------------------------------------------------
y = -1/3 x + c
--------------------------------------------------
Find y-intercept
--------------------------------------------------
y = -1/3 x + c
at point (6, 5)
5 = -1/3 (6) + c
5 = - 2 + c
c = 5 + 2
c = 7
--------------------------------------------------
Insert y-intercept into y = -1/3x + c
--------------------------------------------------
y = -1/3 x + 7
--------------------------------------------------
Answer: y = -1/3 x + 7 (Answer B)
