Answer:

34.78 feet

Step-by-step explanation:

1) using the cosine function, I did cos(43)=x/51

This is because cosine is equal to adjacent over hypotnuse

Once I found x, I used the pythagorean theorem to get 34.78 feet

Some things we should know before we start:

  • Parallel lines are lines that never meet and which are straight.
  • Perpendicular lines are lines that intersect at a 90° angle.

A picture of different types of lines will be shown below

A picture of the graph will be shown below.

Looking at the graph, we can see that lines intersect and seem to have a 90°.

Therefore, they are perpendicular.

Best of Luck!

a vacuum cleaner is marked to sell for Rs 12000 after 12% discount is given and then vat is added if the customer paid Rs 12144
bonufazy [111]

The rate of VAT on the vacuum cleaner is 15%

<h3>How to determine the rate of VAT?</h3>

The given parameters are:

Selling price = Rs 12000

Discount = 12%

Amount Paid = 12144

The amount paid is calculated as:

Amount Paid = Selling Price * (1 - Discount) * (1 + VAT)

So, we have

12144 = 12000 * (1 - 12%) * (1 + VAT)

Evaluate the difference

12144 = 12000 * 0.88 * (1 + VAT)

Evaluate the product

12144 = 10560 * (1 + VAT)

Divide both sides by 10560

1.15 = (1 + VAT)

Subtract 1 from both sides

VAT = 0.15

Express as percentage

VAT = 15%

Hence, the rate of VAT on the vacuum cleaner is 15%
