Respuesta :
I can try to answer this to the best of my knowledge
so if angle A is 140 degrees) then the other two angles *together* add up to 40 degrees)
so both B and C are less than 40.
that means their sides are less than the side opposite angle A
, so less than 3. But they tell you b is 10. hope it helps
It would be no solution because none of the options would work. All triangles add up to 180° and since the angle is 140°, both of the other angles have to equal 40° total between the two.
Hope this helps!
