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.
Another interesting right triangle is the 30-60-90 degree triangle. The ratio of this triangle's longest side to its shortest side is two to one.. That is, the longest side is twice as long as the shortest side. It too is manufactured in plastic and widely used in design, drawing, and building applications.
