In the diagram, which angles are vertical angles? check all that apply.
abe and abc
abe and cbd
abe and ebd
abc and ebd
abc and cbd

If two line crosses, then the vertical angles are the angles opposite each other. In this way, these angles share the same vertex. So, the vertical angles are always equal. Therefore, in this problem, the right answers are:

1. ABE and CBD

Notice that the vertex is B, so these two angles share the same vertex. Accordingly, these two angles are vertical angles.

2. ABC and EBD

The same reasoning is applied here. The vertex is also B. Notice that the angles CBD and ABD add up to 180 degrees.

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
