Answer:

Step-by-step explanation:

Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.

Victoria bought a jacket in the sale which had 20% off. If it cost ?36 on sale what did it cost before the sale?

Basile [38]

Answer:

The jacket costs $45

Step-by-step explanation:

In order to find this, notice that the price of the sale represents 80% of the total cost. This is because we took 20% away with the sale. Now we can find the overall amount by dividing the sale cost by the amount it represents.

$36 / 80% = $45
