Answer :

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
