The name of the angle is obtuse
Yea they are cuz they have the same side and angle measurements
You would start on 2.5 on a number line and then you would add 4/5 which = I think 4.5 ( not sure ) but you start off with 2.5 then add on 4/5 going to the right!
I’m not sure if that made any sense but Brainly.com appreciated:)
