Answer:
2x +5x-20+3x=180(angle of triangle)
10x-20=180
10x=180+20
10x=200
x=200/10
x=20

<h2>It doesn't change the volume.</h2>
Step-by-step explanation:
If we change the position of the vertex of a cone, it won't change its volume, because we're not changing its height.
When we change the position of the vertex of the cone, we are moving it to left or right, which would give a slant cone. However, its dimensions are the same. The important fact here is that the dimensions of the cone don't change, that's why it would give the same volume.
