The picture shows a barn door.

what is the length of the bar ac?

6 sin 60°

6 cos 60°

Option B is correct.

Length of the bar AC i.e

Step-by-step explanation:

As per the statement:

In right angle triangle ACB

Side AB = 6 feet and

We have to find the length of bar AC:

Using cosine function ratio:

Here,

Adjacent side= AC

Hypotenuse side = AB = 6 feet

then;

substitute the given values we have;

Multiply both sides by 6 we have;

Therefore, the length of the bar

16.80 times .20= 3.36

step-by-step explanation:

80
