Answer:

Step-by-step explanation:

3:4 is the same as 3/4

6 to 9 = 6/9 = 2/3 <=== this is not equivalent

9/12 = 3/4...equivalent

9 to 12 = 9/12 = 3/4....equivalent

15/20 = 3/4....equivalent

24:32 = 24/32 = 3/4....equivalent

Answer: the answer is approximately 41.65428, not rounded (maybe re do all the steps just in case)

Step-by-step explanation:

1. label the space between X and W the unknown.

2. You will be using SOH-CAH-TOA

3. Label the X as the opposite because it is the opposite side of where your degree is located.

4. Label five as adjacent because it’s next to the degree.

5. You will use TOA since you have adjacent and opposite values.

6. Write the equation tan58=x/5, the unknown goes on the top because O is first, the five goes on the bottom because A is last on TOA.

7. After you have the equation time 5 on both sides leaving you out with (5)tan58=x

8. On your calculator time (5)tan58 which will give you x.

The length of a rectangular mural is 2ft. more than three times the width the area is 165 sq. ft. Find the Width And Length

olga nikolaevna [1]

We know that the formula for the area of a rectangle is:

$A=lw$

We know that the area is 165. Now we need to solve for the dimensions.

Let the width of the rectangle be " $x$ "

Then the length of the rectangle is $3x+2$

Substitute.

$(3x+2)(x)=156$

Multiply the terms.

$3x^2+2x=156$

Bring the 156 over.

$3x^2+2x-156=0$

We have to use the quadratic formula to solve this now. Let us restate it:

$x= \frac{-b± \sqrt{b^2-4ac} }{2a}$

Now I'm going to fast forward this because all the rest is boring stuff and substitution. The answer is:

$\frac{ \sqrt{469}-1 }{3}$

Since we cannot have a negative answer, we must cancel out the other answer, which I did not include.

Hope this helped! :)
