In Triangle DEF, DE = 8cm and Angle D= 60 degrees. When EF = 7 cm, how many triangles are possible?

    two
    If DF=4 we have a right triangle, with EF=4√3 = 6.92

    Moving F a bit toward D will enable us to make EF a bit longer (7.00)

    Moving F a bit away from D will allow for EF a bit longer (7.00)
