Answer:
x-int (6.2, 0)
y-int (0, 3.1)
Step-by-step explanation:
x-intercept is found when y = 0.
y-intercept is found when x = 0.
Step 1: Define equation
2x + 4y = 12.4
Step 2: Find x-intercept
<em>Substitute y for 0.</em>
2x + 4(0) = 12.4
2x = 12.4
x = 6.2
(6.2, 0)
Step 3: Find y-intercept
<em>Substitute x for 0.</em>
2(0) + 4y = 12.4
4y = 12.4
y = 3.1
(0, 3.1)
Triangle has a total of 180 degrees
add up all angles
A+B+C = 3x+5+4x-2+2x+6=180
9x=171
x=19
Plug x values into the A , B and C expressions and you get your answers

Answer:
37.70 feet
Step-by-step explanation:
-The radius of each tire is given as 6 feet.
-Distance around each tire is equivalent to the circumference of each tire.
#Circumference is calculated as:
![C=\pi D=2\pi r\\\\=2\pi \times 6 \\\\=12\pi\\\\=37.70\ feet](https://tex.z-dn.net/?f=C%3D%5Cpi%20D%3D2%5Cpi%20r%5C%5C%5C%5C%3D2%5Cpi%20%5Ctimes%206%20%5C%5C%5C%5C%3D12%5Cpi%5C%5C%5C%5C%3D37.70%5C%20feet)
Hence, the distance around each tire is 37.70 feet
