As the triangles are similar corresponding sides are in the same ratio
So we have:_
24/6 = (30-2x) /x
4x = 30-2x
6x = 30
x = 5
2(x-7)-10=12-4x
2x-14-10=12-4x
2x-24=12-4x
2x-12=-4x
-12=-2x
6=x
It equals to:
(3(a+h)^2 - 3a^2) / h = 3(2ah+h^2) / h = 6a + 3h
The 3D prism that produced the cross-section of a triangle is a triangular prism.
<h3>How to describe the 3D prism?</h3>
From the given figure, we can see that the cross-section is a triangle
One of the faces of a triangular prism is a triangle.
This means that when the triangular prism is cut vertically, a triangle face is created
Hence, the 3D prism that produced the cross-section of a triangle is a triangular prism.
