Exterior
For example
You have a triangle with angles 20 30 and 130
The exterior angle of 130 is 50 as 130+50=180
Angles on a straight line =180
20+30=180-130
Answer:

Answer:
The volume of the pyramid is 
Step-by-step explanation:
we know that
The volume of the pyramid of the figure is equal to

we have

----> the height must be perpendicular to the base
substitute

So because the factors of the equation are (x-2), (x+3) and (x-3), you set them equal to zero and you get x=2, -3, and 3
