Help

A triangle is 180 degrees no matter what (all of the angles will add to make 180)

so

       180-130=50

and 50/2=25

 so the angles are 25 degrees, 25 degrees and 130 degrees 

if u add them all up again u get 180 degrees 

hope that helps!!!

25 and 25

180 - 130 = 50, for the 2 sides. So, 50/2=25.
