A prism is a polyhedron comprising an n-sided polygonal base, a second base which is a translated copy (rigidly moved without rotation) of the first, and n other faces (necessarily all parallelograms) joining corresponding sides of the two bases (called lateral faces).
Hence:
1. if t<span>he base of a prism has n sides, then the prism has n lateral sides;
</span><span>
</span><span>2. by the definition, a prism has 2 equal bases and from the first part it has n lateral faces that together form n+2 faces.

Answer:
40, 60, 80
Step-by-step explanation:
The sum of angles in all triangles is 180 degrees (assuming you are talking about Euclidean geometry). If 2:3:4 is the ratio then
2x + 3x + 4x = 180
9x = 180
x = 20
Now that we now what x is, we can find the respective angles by plugging the value of x in. The angles are 40, 60, and 80 respectively.
Then the two negatives would combine to create a positive.
