We assume, that the number 28.52 is 100% - because it's the output value of the task.
<span>2. We assume, that x is the value we are looking for. </span>
<span>3. If 28.52 is 100%, so we can write it down as 28.52=100%. </span>
<span>4. We know, that x is 36.8% of the output value, so we can write it down as x=36.8%. </span>
5. Now we have two simple equations:
1) 28.52=100%
2) x=36.8%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
28.52/x=100%/36.8%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 36.8% of 28.52
28.52/x=100/36.8
<span>(28.52/x)*x=(100/36.8)*x - </span>we multiply both sides of the equation by x
<span>28.52=2.71739130435*x - </span>we divide both sides of the equation by (2.71739130435) to get x
<span>28.52/2.71739130435=x </span>
<span>10.49536=x </span>
<span>x=10.49536</span>
Answer:
180°
cuz when a line (I forgot the name) and radius meet at the circumference they from an angle of 90°
