emperor of Rome (284-305) who divided the Roman empire into east and west (286) in an attempt to rule the territory more effectively, appointed two rulers for each section with direct sub-rulers for each, appointed a co-emperor which lead to power struggle, army leader and the son of a slave who tried to restore order to the empire.
A right angle triangle always consists of one 90 degree angle, and every triangle must equal 180 degrees. Here is the work for this problem: 90 degrees (representing the right angle) + 50 degrees equals 140 degrees. 180 minus 140 equals 40. Therefore, the remaining angle would be 40 degrees.
Sure - a triangle could have 40, 70 and 70 degree angles. There's probably an infinite more amount of those. not possible,for a triangle the sum of three angles should be 180 degree. so even one side has 0.1 degree the other can only have 90 degree and 89.9 degree.so it is not possible.
