5t=v-u (Subtract u on both sides)
t=(v-u)/5 (Divide by 5 in both sides)
 
        
             
        
        
        
<u>Given</u>:
Given that the measure of ∠CDR = 85°
We need to determine the measure of  and
 and 
<u>Measure of arc RC:</u>
Since, we know that if a central angle is formed by two radii of the circle then the central angle is equal to the intercepted arc.
Thus, we have;

Substituting the values, we get;

Thus, the measure of  is 85°
 is 85°
<u>Measure of arc CBR:</u>
We know that 360° forms a full circle and to determine the measure of arc CBR, let us subtract the values 360 and 85.
Thus, we have;

Substituting the values, we have;


Thus, the measure of  is 275°
 is 275°
 
        
             
        
        
        
Answer:
100° it has to be a 
 length of 20 or like my 100 worlds longest
 
        
                    
             
        
        
        
Hello!
1.
find circumferece
c=2pir
c=2*6*pi=12pi
intercept is 5.4
2pi radians=all
part/whole=part/whole
5.4/12pi=x/2pi
times both sides by 12pi
5.4=6x
divide both sides by 6
0.9=x
answer is 0.9 radians
2. 
assuming 9pi/5 radians
find circumference
c=2pir
c=2*26.9*pi
c=53.8pi
arc/circumference=(9pi/5)/2pi
x/(53.8pi)=(9pi/5)/(2pi)
x/(53.8pi)=18/5
times both sides by 53.8pi
x=608.46266 m
about x=608.46 m
Hope this Helps! Have A Wonderful Day! :) 
        
             
        
        
        
You can fit 2 in each or 3 can have some in it
