Angle E = 180 -45 -63 = 72 degrees
Using the Law of Sines
FD / sine (E) = ED / sine (63)
3.8 / 0.95106 = ED / 0.89101
side DE = 3.8 * .89101 / .95106
side DE =

Answer: 40 cm^3
Step-by-step explanation:
The volume of a triangular prism is the base * height.
Therefore, the volume is 50 cm^2 * 8 cm = 40 cm^3
Answer:
length of segment AB is 13
OR
AB = 13
Step-by-step explanation:
Use the Pythagorean Theorem with c being the length of segment AB.
a^2 + b^2 = c^2
5^2 + 12^2 = c^2
169 = c ^2 (square root both sides to get c by itself)
13 = c
