Imagine a standard wall clock. 2:00 is an acute angle, 3:00 is a right angle, 4:00 is an obtuse angle, 6:00 is a straight angle, 7:00 is a reflex angle: greater than 180 degrees.

Oh, dude, a reflex angle is greater than 180 degrees, so if you draw one arm of the angle straight, the other arm would have to be pointing backwards, which is like, not really a thing in normal geometry. So, technically, no, you can't have a straight angle and a reflex angle sharing an arm. But hey, if you're feeling creative, go for it, who am I to stop you?
Yes, it is possible to draw a quadrilateral with a reflex angle and an obtuse angle. A reflex angle measures more than 180 degrees, while an obtuse angle measures between 90 and 180 degrees. To create a quadrilateral with these angles, you can draw a shape with one reflex angle (greater than 180 degrees) and one obtuse angle (between 90 and 180 degrees), along with two acute angles (less than 90 degrees).
It is 10 degrees more than a straight line so its a reflex angle.
A 190 degree angle is a reflex angle.
360 minus 245 = 115 the measure
