Hi there!! Well that net forms a pentagonal pyramid, because it has 5 sides. Hope that helps!! :)

Theorem: angle (x) formed by intersecting secants (MAB and MDC) is half of the difference of the far arc (BC) and the near arc (AD).

Expressed as a formula,

x=(arc BC - arc AD)/2

=(60-10)/2

=25 °

**Answer:**

Brand A is the better deal!

**Step-by-step explanation:**

Let's start by comparing.

We know brand B has the following cost: 5 ounces = $3.75

10 ounces $7.50 and 16 ounces = $12

Now check the graph.

6 ounces cost $3

12 ounces cost $6

20 ounces cost $10

I don't think we need to look any further but brand A is the better deal!
