1) The scale factor for the dilation is 2/3.
2) The polygon became smaller after the dilation because you are multiplying by a scale factor less than 1.
3) The ratio of the areas is 2/5.
Answer:
1 - SSS
Step-by-step explanation:
We need either two sides one angle, two angles one side, or three sides to prove congruency. In this case we have 3 sides so therefore this is congruent by the SSS theorem.
Answer:
V= 392 ft^3
Step-by-step explanation:
We know that the volume V of a pyramid is one-third the area of the base B times the height h.
If h= 8ft and areabase = 7ft x 7ft = 49 ft^2.
Then, the Volume V is:
V = areabase x height = 49 ft^2 x 8ft = 392 ft^3
So the solution is option D.
