You have to mulitply 2 x 4 + 1 = 9 and 4 is going to be the denomiator and how much can 3 can go into 9 only 3 times and that going to be on top of the denomiator and 2 x 3 = 6
A) Ang 1 + Ang 2 = 90 B) Ang 1 = Ang 2 + 20 B) Ang 1 -Ang 2 = 20 then adding this to equation A produces 2 Ang1= 110 Ang 1 = 55 degrees Ang 2 =35 degrees
