Basic property of triangles:
the largest side is opposite the largest angle
the smallest side is opposite the smallest angle
etc
since angle A is 125° , the sum of the other two angles must be 55°
that is, "a" must be the largest side, but b > a
which would mean angle B > angle A
But we can't have 2 obtuse angles, so ....
no such triangle is possible
Determine the number of triangles that could be drawn with the given measure. Then, find the measures of the other angles and the other side in each possible triangle. Round side lengths to the nearest tenth of a unit and angle measure to the nearest tenth of a degree, where necessary. a) triangle ABC, where angle A=125', a=3m, b=5m.
