Step-by-step explanation:
hope this is good...
You need to simplify it by 8
5 is a common factor on both of them
Right triangle = has a 90 degree angle
Acute triangle = has angles less than 90 degrees
Obtuse = has angles more than 90 degrees
Equiangular triangle = all angles are the same amount of degrees
Hope this helped!
