Asked by Jeremy
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?

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.
