Question

Find all solutions for a triangle with A=140, b=10, and a=3. Round to the nearest tenth.

Answer 1

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!

Answer 2

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
