<h3>
Answer: 226 degrees</h3>
=====================================================
Explanation:
Notice the tickmarks on the segments in the diagram. This tells us that chords DC and CB are the same distance from the center. It furthermore means that DC and CB are the same length, and arcs DC and CB are the same measure
arc DC = arc CB
12x+7 = 18x-23
12x-18x = -23-7
-6x = -30
x = -30/(-6)
x = 5
---------------------
Use this x value to find the measure of arcs DC and CB
- arc DC = 12x+7 = 12*5+7 = 67
- arc CB = 18x-23 = 18*5-23 = 67
We get the same measure for each, which helps confirm we have the correct x value.
The two arcs in question add to 67+67 = 134 degrees. This is the measure of arc DCB. Subtract this from 360 to get the answer
arc DAB = 360-(arc DCB) = 360-134 = 226 degrees
I'm using the idea that (arc DCB) + (arc DAB) = 360 since the two arcs form a full circle.
the answer is 27 because all you have to do is divide 810 by 30 which equals 10 times three dollars at the equals 30 soda by 830 and 30 parts and equals 27 soap and try to answer or problem only calculator at home on your phone to add on your tablet on your computer and a half thank you
OK for number 3is 70because you add the number that they give you and then subtract 36 106 and you get your answer
8th payment, if you want how to get the answer I made a chart as shown in the picture
