Answer:
1) Parellel because if she had sliced perpendicular, she would have gotten a square and a triangle.
2) Perpendicular because if she had sliced parallel, she would have gotten a (once more) square and a triangle.
1) First shape and Last shape (the cylinder and the cone).
2) First shape and Second shape (the pyramid and the cone).
1) This would be a cone - I included a picture of it.
2) This would be a triangular pyramid - I included a picture of it.
Answer:
54 cm
Step-by-step explanation: 1/2b x h
1/2(18) x 6
9 x 6=54
Answer:
The distance from an edge of a circle to another edge
Step-by-step explanation:
48 I think. If they each get 1/3 of the sweets (which is 16), then it's 16 x 3.

Answer:
x = 12
Step-by-step explanation:
We can find x using either the measure of angle B, or the measure of angle A.
Using A, we have ...
48 = x^2 -8x
Adding 16 completes the square:
64 = x^2 -8x +16 = (x -4)^2
Then the positive solution is ...
√64 = x -4
x = 4 +8 = 12
The triangles are similar when x=12.

We expect angle B to be 84° when x=12:
(x^2 -5x) = x(x -5) = 12(7) = 84 . . . . as needed
