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

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.
