In any triangle ABC, E and D are interior points of AC and BC,respectively. AF bisects angle CAD and BF bisects angle CBE. Prove that measures (AEB) + measure (ADB) = 2x measure of (AFB).
A dead body was found within a closed room of a house where the temperature was a constant 24° C. At the time of discovery, the core temperature of the body was determined to be 28° C. One hour later, a second measurement showed that the core temperature of the body was 26° C. The core temperature of the body at the time of death is 37° C
A. Determine how many hours elapsed before the body was found.
