Step-by-step explanation:
We can set up the ration of the radian angle θ in your problem in terms of degrees given as the ratio: (Θ/2·pi) = (72/360), solving for Θ we get Θ = 1.26 radians. Then for the arc length s = Θ·r using this value gives s = 1.26·4 = 5.04
The answer is 1 cause 1/2 times 2 sides. Just draw a square with side lengths of 1/2
-3x+1 just do the opposite
y = mx + b, where b is the y intercept.
D, or "12" is the answer.
Best of luck.
