Yes it was reasonable. I say it is resonable because if you multiply 44 times 25 it is 1,100 so the estimate was close enough
The answer is B... good treads claim is false therefore it can be concluded that speed tracks tires last longer than good treads tires
234 millimeters^2 is your answer
Slope: 3/2
Y-Intercept: -3
X + y = 180
x = 4y
Plug that in and you get: 4y + y = 180
5y = 180
y = 36
If you want the larger angle, simply plug in y to x = 4y
So: x = 4(36) = 144
The smaller angle is 36 degrees, and the larger angle is 144 degrees.
