    A. EG = √3 * FG

    D. EG = √3/2 * EF

    E. EF = 2 * FG

    Step-by-step explanation:

    ∵ tan 60 = √3

    ∵ tan60 = EG/GF

    ∴ EG/GF = √3

    ∴ EG = √3 * GF ⇒ A

    ∵ m∠F = 60°

    ∵ sin60 = √3/2

    ∵ sin 60 = EG/EF

    ∴ √3/2 = EG/EF

    ∴ EG = √3/2 * EF ⇒ D

    ∵ cos60 = 1/2

    ∵ cos60 = GF/EF

    ∴ GF/EF = 1/2

    ∴ EF = 2 * GF ⇒ E
