For ΔABD, it is given that side AB is congruent to side CB, that ∠ABD is congruent to ∠CBD. In order to invoke the SAS Postulate, the remaining side(s) fo the triangles must be shown to be congruent. Those sides are BD and BD.
The appropriate choice is ...
... b. BD ≅ BD
2x+4x-4=80
6x-4=80
6x=84
84/6=14
Angle c = 4 x 14= 56 - 4 = 52
Hope this helps.
Hey there!
First, you would need to find the area of the circle/pizza . . .
Formula of finding area → pi*r² (Pi * the radius of the circle/pizza²)
---
Once you have found the area, you would need to divide the result by the number 12 since there is a total of 12 slices in the pizza.
---
This is how you would find the area of one slice of pizza.

Answer:
I have the same homework and I could do it either
Step-by-step explanation:
<span>y= -x^2 + bc + c represents a vertical parabola that opens down. As x approaches either + or - infinity, the function approaches - infinity. Imagine an upside down parabola; doing so will confirm this answer.
