Answer:
x = 21
Step-by-step explanation:
Vertical angles are congruent, this
3x - 30 = 2x - 9 ( subtract 2x from both sides )
x - 30 = - 9 ( add 30 to both sides )
slope = -3/2
y intercept = (0,0)
equation, y = -3/2x+0
y2-y1/x2-x1 = -3-3/2--2 = -6/4 = slope = -3/2
235.62 cubed yards
Area of a cylinder = pi(r^2)*h
pi(5^2)*3 = 235.62
