What is the length of EF

The length of EF = x = 12.8 feet

Step-by-step explanation:

Given

So we have to determine the length of EF.

As

EF = x

Using the formula

Sin 19⁰ = x / 40              ∵ EF = x = Opposite

0.32 = x / 40

x = 0.32 × 40

x = 12.8 feet       (Rounded to the nearest 0.1 or  the Tenths Place)

Therefore, the length of EF = x = 12.8 feet
