2. Find the difference between the largest and smallest angles of a triangle if the lengths of sides are 10, 19 and 23.

Solution

The angle opposite to the largest side is the largest angle. (...a=23(largest))
\ Ð A is the largest angle.

Thus, the difference between the largest and smallest angles is 1000 18' - 250.20' = 740 58'
