The height and base dimensions of a pyramid are shown in the diagram. what is the volume of the pyramid? a. 30 cubic unitsb. 40 cubic units c. 50 cubic unitsd. 60 cubic units

i can answer this question sweetie!

step-by-step explanation:

it is true

step-by-step explanation:

all the combinations add up i used   calculator

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
