*** Sorry instead of writing 170 I wrote 270 for the big angle.. other than that it's correct
or another way to solve this is....
we know that a straight line is 180 degrees and the angle APD is 170 all we need to do is subtract 170 from 180 to get the answer of DPB

Answer:
8/35
Step-by-step explanation:
The volume of the triangular prism is 66 cubic inches.
In order for us to know the volume of the triangular pyramid, first we need to know the ratio of the volume of triangular prism and the volume of the triangular pyramid.
Volume of the pyramid = 1/3 * volume of the prism.
Volume of the pyramid = 1 / 3 * 66
<span>Volume of the pyramid = 22 cubic inches.

So the volume of the triangular pyramid is 22 cubic inches.
