+48 Hello, I just have 2 questions. If you could help me out, then thank you :)
1. This figure shows circle Z with chords AB and RS.
M(arc)AR=55dg
M(arc)RB=66dg
AB=8m
RS=8m
What is m(arc)RS?
2. This figure shows circle with diameter QS.
m(arc)RQS=280dg.
What is the measure of
+129896 1. Equal chords in a circle span equal arcs..........
The arc spanned by AB = 55 + 66 = 121°
And since RS = AB.....it spans the same arc RS = 121°
2. I assume you want to know m(arc) RS??? If so, it equals 360 - 280 = 80°
+37152 Since the chords are the same length the arcs are the same degrees
m(arc)RS = 66+55 = 121 degrees
Your second question has a typo or something arc RQS ????? I s that supposed to be ROS ???
+37152 Sorry...I see now what you are asking....
If RQS is 280 degrees RS is what is lefft from 360 degrees 360-280 = 80 degrees = RSarc
