A pyramid and a cone are both 12 centimeters tall and have the same volume. What statement must be true about the two solids? A. The horizontal cross-sections of the prisms at the same height must have the same area. B. The vertical cross-sections of the prisms at the same width must have the same area. C. The area of the cross-sections of the prisms are multiples of each other. D. The cross-sections of the prisms are the same shape.

282 6/7 cm^2

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
