Yes.
It is the line from 0 to 130 degrees on your protractor
Well, 40 degrees is already given.. And the angle "R" I assume has a box in its corner, that represents a 90 degree angle. as for I.E: "L" <-- is a 90 degree angle. so you add 40 + 90 = 130. In all triangles will always = 180 degrees. No if and's or but's about it. so you would take your 130 degrees subtract from 180 degrees, 130 - 180 = 50! and that will decipher your answer your looking for.
130 angle
An obtuse angle
Yes.
Any polygon can have a 130-degree angle. It doesn't have to, but it can.
130 degree angle
An angle of 130 degrees is an obtuse angle
130 degrees
Acute
the completment of a 65 degree angle is 130
130 degrees
It is the line from 0 to 130 degrees on your protractor
It's larger than 90 degrees, so we call it an "obtuse angle."

Supplement of 130 deg = 180 - 130 = 50 deg Complement of 50 deg = 90 - 50 = 40 degrees
