sinC/c = sinA/a
sinC = 6.1*0.342/2.1 = 0.993
That is so close to 1, I'd say C=90°
So, yes, you are correct. Just a single right triangle does the trick.
Determine how many triangles can be drawn. Calculate, then label, all side lengths to the nearest tenth and all interior angles to the nearest degree.
a= 2.1 cm, c= 6.1 cm, <A=20 degrees.
Isn't height c sin A and therefore h=2.1 cm and therefore only 1 90 degree triangle is possible?
