Hello,
When you have a polygon inscribed in a circle, the opposite angles are supplementary.
So we can start by saying that A + C = 180. Or x + 3x = 180. This gives us a value of 45 for x.
If we input that in for angle B, we get: 2(25) - 10 = 80.
If angle B = 80, then angle D must be 100, because the angles are supplementary.
Good luck,

Arianna sold for $ 299.6
<em><u>Solution:</u></em>
Given that, Part of Arianna’s earnings are based on a 5% commission rate
At the end of the day arianna earned 14.98 in commission
Therefore,
Commission earned = $ 14.98
Commission rate = 5 %
Let "x" be the amount that Arianna sell that day
Therefore, according to question,
5 % of amount earned = 14.98
5 % of "x" = 14.98
<em><u>Solve the above equation for "x"</u></em>

Thus arianna sold for $ 299.6
Answer:
i think it's c but I'm not 100% sure
Answer:
A
Step-by-step explanation:
Round and estimate the sum.
3.41 + 8.051
3 + 8 = 11
3.65 + 7.992
4 + 8 = 12
4.25 + 8.103
4 + 8 = 12
4.89 + 7.431
5 + 7 = 12
The first option is correct.
