we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=![\frac{1}{2} *(arc\ AB+arc\ CD)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A%28arc%5C%20AB%2Barc%5C%20CD%29%20)
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=![\frac{1}{2} *(82+48)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A%2882%2B48%29%20)
m∠CED=![\frac{1}{2} *130](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%2A130%20)
m∠CED=
°
therefore
<u>the answer is</u>
m∠CED=
°
67 millimeters is the wingspan in milli.
Ok so
Knowing that 1 metre consists of 100cm,
You can conclude and agree that 8 cm is 8/100, correct?
Now, when converting fractions to decimals, it makes it easier out of 100 or 10. Since it's out of 100 already, you take the amount of zero's in 100 (two) and you move the decimal point (2) places to the <em /><u>left<em /></u>
This gives you 0.08
So the fraction is 8/100, which then can be simplified to 4/50, then to 2/25
and the decimal is 0.08.
