The complete question in the attached figure
we know that
[arcs rc +arc cs arc sm]---------------> they take up half a circle-------->180°
<span> they are all congruent
so 
divide 180 by 3 ----------------> 180/3=60</span>°
Find the length of arc rc=60°<span>
if 360</span>°----------------> (2*pi*7) length of circumference 
60° -------------------> X
<span>X=60*2*pi*7/360------------> 7.327 units
the answer is 
</span>
the length of arc rc= <span>
7.33 units</span>
 
        
        
        
It is an infinite number of solutions. To put it simply, is x = 1, y would equal 4.you can do this with every single number.
        
             
        
        
        
The tangent and cotangent functions of the angle are related such that one is the reciprocal of the other. From the given tan theta = 11 / 60. The reciprocal of this number is 60 / 11. This value is also the cotangent of the angle. Thus, the cotangent angle theta is 60 / 11. 
        
                    
             
        
        
        
Answer:
x=60°
Step-by-step explanation:
angle 135° and (2x+15)° are corresponding and thus are equal
Therefore (2x+15)°=135°
2x=135-15
2x=120°
X=60°
