The value of minor arc, major arc and central angles given below:
What is an arc?
An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc.
Given: BOF= 126
angle BOF= angle COE= 126 (Vertically opposite angle)
Now,
angle BOF + angle BOC= 180 (Linear pair)
BOC=180-126= 54
and, COE= COD+ DOE
= COD+COD
126 =2COD
COD= 63
now, BOD= BOC++COD
= 54+63
= 117
Arc length of BCD= 87/360*2πr
= 2.041r
2. minor arc:
arc BF= 126/360* 2πr
= 2.198r
arc FE= 54/360*2πr
= 0.942r
arc DE= 63/360*2πr
= 1.099r
arc CD= 63/360*2πr= 1.099r
arc CDE=126/360*2πr
= 2.198 r
3. major arc
arc BFED= 243/360*2πr
= 4.239r
arc FBCD= 243/360*2πr
= 4.239r
arc DCBFE= 297/360*2πr
= 5.181r
arc CBFE= 234/360*2πr
= 4.082r
4. 6 central angles
BOC= 54= FOE
COD=63=DOE
BOF=126
