Answer:
DF = 18√3
Step-by-step explanation:
Considering the angle 60⁰, opposite side = DE = 27, hypotenuse = DF = ?
Using Trigonometric ratio,
sin 60⁰ = 27 / DF
DF sin 60⁰ = 27
DF × √3 / 2 = 27 Divide both sides by √3 / 2
DF = 27 × 2 / √3
DF = 54 / √3 By Rationalizing
DF = 54 / √3 × √3 / √3
DF = 54√3 / 3
DF = 18√3
