I understand the answer but wondering why the 180*(n-2) formula doesn't work in this problem. There are six sides so the formula would generate 180* (6-2) = 720 but of course we know the figure is just two triangles so the answer is 360 (180*2). Please advise, thanks in advance!
Ah I remember this one from MGMAT CAT 4. Nice lil problem
The figure is basically just 2 triangles. Triangles add up to 360degrees.
720degrees would be four triangles.
ans is D.
