The height of the parallelogram is 6.4 m.

<h3>What is a parallelogram?</h3>

A parallelogram is a quadrilateral. Let us recall that a quadrilateral is a four sided figure. It is also important to recall that the opposite sides of a parallelogram are equal.

Let us now try to find the height of the parallelogram;

Given that;

/DE/ = /AC/

10 = /BC/ + /AB/

/AB/ = 10 -  /BC/

/AB/ = 10 - 6

/AB/ = 4 cm

Then;

/AE/= /CD/ = 5 cm

Using the Pythagoras theorem;

/EB/^2 = /AE/^2 + /AB/^2

/EB/ = √/AE/^2 + /AB/^2

/EB/ = √(5)^2 + (4)^2

/EB/ = √ 25 + 16

/EB/ = 6.4 m

A pair of shoes usually sells for $69. If the shoes are 30% off, and sales tax is 8%, what is the total price of the shoes, incl
hodyreva [135]

Answer:

52.16

Step-by-step explanation:

So, Lets find out the discount first. Since the shoes are 30% off, that means the shoes are 70% of their original price, so lets multiply the original price of 69 by .7. 69*.7=48.3

Now to find the sales tax we need to multiply the price we got finding the sale by 1.08 since the sales tax is added on not removed from the price. 48.3*1.08=52.16

The prices after the sale and including tax is 52.16
