ΔACD and ΔASR are the same so we can write a ratio:

x/4 = 10/5

x/4 = 2

x/4 * 4 = 2 * 4

x = 8

Since AS is equal to x, they are both the same.

Therefore, the answer is [ x = 8, AS = 8 ]

Best of Luck!

timama [110]

Answer:

Roberta earns $164.4 on an 8 hr shift.

Step-by-step explanation:

In one hour  Roberta makes $9

So if she works for 8 hours she will be making

=> ( 9 X 8)$

=>72$

Also she earns a commission of 10.5% on selling a jewellery  worth $880

So 10.5% of 880 is

=> \frac{10.5}{100}\times 880

=>  0.105\times 880

=> 92.4

Hence  Roberta will be earning a total amount of

(72+ 92.4)

=>$164.4
