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.
there are exactly 180 degrees in a triangle, no matter if it is an obtuse, acute or right triangle. The some of all the angles in a triangle will always be 180 degrees. Of course, there are exceptions to this. The angles of a triangle are 180 degrees only when drawn on a plane. If you were to draw a triangle on a curve surface, then the angles wouldn't add up to 180 degrees. Take for example, Earth.
