Best ResponseYou've already chosen the best response.0now for hte botom anglesdw:1361560354038:dw these are also supplementary meaning that the angle next to 48 is (18048)= 132

Best ResponseYou've already chosen the best response.0since we found 132 lets leave that one out as we only need two to solve this \[2xy=180\] \[x+y=132\] if you add the two together you get \[3x=312\] \[x=104\] using this in the second equation we get \[104+y=132\] \[y=28\] now lets test these values with the 3rd equation we got finding the 132 angle \[x2y+132=180\] \[1042(28)+132=180\] \[180=180\] therefore these answers are correct
