Answer:
Step-by-step explanation:
The applicable formula is ...
s = rθ
where s is the arc length, r is the circle's radius, and θ is the central angle in radians.
Filling in the given values, we find ...
15 = 6θ
θ = 15/6 = 2.5 . . . radians
Pi (π) radians is 180°, so the angle in degrees is ...
2.5(180°/π) ≈ 143.24°
Triangles are anything with three vertexes and three angles to it and are always closed.
Quadrilaterals are anything with four vertexes and four angles on them and are always closed. Examples include a square, rectangle, trapezoid etc.
74/258 = %/100 , cross multiply 74 times 100 then divide by 258 = 28.6821705 , rounding it gets you to 28.7%. The answer is D.
