Answer:
Step-by-step explanation:
arc BE is the same as the interior angle, or 76°
BE = 76 °
we can also find arc CE the same way, b/c we can see that the interior angle is the suppment with 76 or 180-76 = CE or 104°
Now we know all the arcs but arc CD
so use the idea that all the way around the circle is 360°
360 = 76 + 104 + 140 + CD
360 - 76 - 104 - 140 = CD
40 = CD
CD = 40 °
Looks good, since b c and d don't really match up answer a looks like the proper choice for you
It doesn't change because to add fractions, you need a common denominator. To find it, they multiplied 1/3 by 2 to make 2/6, to add to the 3/6.
