Anya started solving for the volume of the pyramid using the steps below. V = one-third B h B = 12 (12) = 144 feet squared A square pyramid with a base of 12 feet by 12 feet and height of 15 feet. What is the final step in determining the volume of the pyramid? V = one-third (144) (15) V = one-third (144) (12) V = one-third (144) V = one-third (12) (15)

A) i got it right in edg

Step-by-step explanation:

A)1/3(144)(15)

Step-by-step explanation:

When you find the area of the base of a pyramid, you have to multiply this by the height. Then find one third of the product of your base and height.

Hope this helps

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1
