The length of segment EF is 12 cm. Which statements regarding triangle DEF are correct? Check all that apply.

Answer 1

Triangle DEF is the right triangle with angles:
90°, 60°, 30°.
EF = 12 cm
DE = 1/2 · EF = 1/2 · 12 = 6 cm
DF = EF √3 / 2 = 12√3 / 2 = 6 √ 3 cm ≈ 10.4 cm
Answer:
DE = 6 cm,
DF = 6 √3 cm
