C. None of the x-values repeat.
Answer:
alternate angles will be equal, so x = 60
Step-by-step explanation:
it's an equilateral triangle. all angles are equal to 60°. one of them is alternate to x as per the figure, so x = 60°
V = 1/3 area of base * height
Area of base = h [(b₁ +b₂)]/2
[(3 + 6) * 4] : 2 =
18 ft²
Volume =
18 * 3 =
54 ft³
