Answer:

x = 8

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{BC}{EF}$ = $\frac{CD}{FG}$

Note that ΔBCD is a 3- 4- 5 triangle ( Pythagorean triple), hence CD = 4

Substitute given values into the equation

$\frac{3}{6}$ = $\frac{4}{x}$ ( cross- multiply )

3x = 24 ( divide both sides by 3 )

x = 8

<h3>How to calculate total money spent ?</h3>

To calculate total money spent we have to add all the money we spent on all things.

Given that Ted has $55. 00 in his pocket.

(i)

two books for $29. 95 each

Money needed for 2 books = $2\times 29.95=59.9$

So Ted is not able to purchase 2 books

(ii) headphones for $29. 99 and a portable speaker set for $30. 95

Money needed for headphones and portable speaker = 29.99+30.95=60.94

So Ted is not able to purchase headphones and portable speaker

(iii) an MP3 player for $35. 99 and a $20. 00 gift card for downloading music

Money needed for MP3 player and gift card= 35.99+20.00=55.99

So Ted is not able to purchase MP3 player and gift card

(iv) three books for $16. 99 each.

Money needed for 3 books = $3\times16.99$ =50.97

So ted is able to purchase these three books .
