∠e∠e and ∠f∠f are vertical angles with m∠e=9x+12m∠e=9x+12 and m∠f=3x+24m∠f=3x+24 . what is the value of x?

Since ∠E and ∠F are vertical angles, they are congruent, meaning that m∠E = m∠F

Plugging in the equations that were originally given, we can form the equation 9x + 12 = 3x + 24

Subtract both sides of the equation by 3x

6x + 12 = 24

Subtract 12 from both sides

6x = 12

Divide both sides by 6

x = 2

This should be your answer. Have an awesome day! :)

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
