Answer:
22.143
Step-by-step explanation:
49.419-27.276=22.143
Using proportions, it is found that the measure of the inscribed angle B is of 30º.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In a circle, the inscribed angle is half the measure of the outside angle. Hence, in this problem, the measure of angle B is of 50% of 60º, hence:
m<B = 0.5 x 60º = 30º.

Answer:
4
Step-by-step explanation:
r = 255
r = R-2RF/W
R = 1,750
F = 63.2
W = 148
Now, we need to plug the values in to substitute the variables with real numbers.
r = 1750-2(1750 x 63.2)/148
First, solve for the parentheses.
r = 1750-2(110600)/148
Second, multiply by 2.
r = 1750-221200/148
Next, divide by 148.
r = 1750 - 1494.594
Then, we subtract.
r = 255.406
Lastly, we round it to the nearest whole number.
r = 255
