180 is the total of all the angles added together so if you subtract the 122 from 180 and divide by 2 you can get 29 for both and if you add it all together you should get 180 :)
pretty ez, so like a triangle got 180 degress total. what u gota do my man, is substract 122 from it. And u get 58 and they both are equal so u divide by 2 and u get 29.
