12. The answer is B because the sum of any two sides of a triangle must be greater than the other side. A. 4 → 4 + 4 is not GREATER than 8 B. 8 → 4 + 8 is greater than 8 and 8 + 8 is greater than 4 C. 12 → 4 + 8 is not GREATER than 12 D. 16 → 4 + 8 is not GREATER than 16
13. The central angle containing the green beans is 360° - (195°+98°) = 67°. If the diameter of the circle is 12 then the circumference = πd = 12π. [tex] \frac{67}{360} [/tex]× 12π≈7.013 So the correct answer is A 67/360 represents the portion of the circle which is green beans and you multiply it by the circumference to find the length of that arc.
