Given c = 73° 41 35, and b =99° 17 33, to project the triangle andcompute the other… … EXERCISES IN SOLVING EIGHT ANGLED TRIANGLES, 83 Projection.—In order to project this case, i.«.,when the two oblique angles are given {105), it ismost convenient to compute the base before pro-jecting. It is also expedient, when two angles aregiven, to project the larger at a point in the…
