Answer:
<u><em>Measure of angle A is 27 7/9 degrees.</em></u>
Step-by-step explanation:
Lets call measure of angle A is <em><u>X-10</u></em>
Lets call measure of angle B is X
Lets call measure of angle D is 2.5X+20
We know that the sum of triangles add up to 180 degrees
X+X-10+2.5X+20=180
X=37 7/9
So measure of angle A is 27 7/9 degrees.
I hope this is right. :)
I believe that the answer is 12.5%
Reason 100% of 80= 80,
So if 80=100%,
then that means 10=x%
Fore it means that,
%=12.5%
George sold:

and Veronica sold:

As expanding the scientific notation numbers, we see that
George sold eight hundred thousand
Veronica sold 4 million
How many time is 4 million of 8 hundred thousand?
We simply divide!

So,
Veronica's song was downloaded 5 times the numebr of that of George.
B is the right answer.
