kondor19780726 [428]

Answer:

The bottle of perfume A contains more glass

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four triangular faces

step 1

Find the surface area of Perfume A

SA=3^{2} +4[\frac{1}{2}(3)(2.5)]=24\ in^{2}

step 2

Find the surface area of Perfume B

SA=2.5^{2} +4[\frac{1}{2}(2.5)(3)]=21.25\ in^{2}

step 3

Compare the surface areas

24\ in^{2}>21.25\ in^{2}

therefore

The bottle of perfume A contains more glass

And they are on opposite side of the transversal, the line crossing the 2 parallel lines?

These 2 angles are alternate interior angles and they are equal, I think you can do the last part by yourself.
