An angle of 90 degrees is a right angle
An obtuse angle is greater than 90 degrees but less than 180 degrees.
X is not a length necessarily, it is merely a "placeholder" for another unknown number. It can also be used to substitute for an expression or it could refer to a line, or an agle, or... Just about anything...
Interior? Exterior? Interior= 180 x (n-2) when 'n' is the number of sides so for a 5 sided shape it is 180 x 3 = 540 degrees. 540=all the angles together 540 divided by the number of sides/angles is 108 Exterior= 360 divided the number of sides/angles (360 divided by 5) = 72 The total agle is 360 degrees but ech exterior agle is 72 degrees
