n. The latter case occurs when B < 90% if the projec-tion of Z> < DC ; and when B > 90% if the projection of J > DC, as will appearfrom Figa. 38, 39. We may observe, also, that there are tico solutions when o and o both fall onthe same side of BB as c ; one solution when o and o… … Fis. 39. 1. Given B = 110°, a = 120°, and 5 = 83°,to project the triangle. See Fig. 39. 2. Given B = 110°, a = 120°, and ^> = 130°,to project the triangle. 3. Given C = 64°, a = 120°, and c = 75°,to project the triangle. 4. Given C = 80°, b = 60°, and c = 40°,to project the triangle. 5. Given 0…
