Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a =
=
·
= 2
2) b² + 5² = 6²
b² = 36-25
b = 
Base = 2
+ 
A = 1/2 x 5· (2
+
)
A = 2.5 · (2
+
)
A = 2.5(8.2)
A = 20.5

Answer:
One of the benefits of Cavalieri's principle is that it allows us to determine the volume of an oblique prism (or oblique cylinder). When dealing with two prisms (or two cylinders), if the base areas are equal and the heights are equal, then the volume is V = Bh regardless of the overall shape.
( i cant see the answers well so estimate to the one that applies)
angle JAB,
dihedral angle is the angle between two intersecting planes. So, the angle with the same measure of the dihedral angle formed by plane DAJ and plane ABC is angle JAB
