Given:
Circle C and circle R are similar.
The length of arc AB is 
The radius of circle C (AC) = 4 unit
The radius of circle R (QR) =6 unit
To find the length of arc QP.
Formula
The relation between s,  r and  is
 is

where,
s be the length of the arc
r be the radius
 be the angle.
 be the angle.
Now,
For circle C
Taking r = 4
According to the problem,

or,  [ eliminating
 [ eliminating  from both side]
 from both side]
or, 
or, 
Again,
For circle R
Taking, r = 6 and  we get,
 we get,
The length of arc QP is 

or, 
Hence,
The length of QP is  . Option C.
. Option C.

Answer:
58.0 degrees
Step-by-step explanation:
Let the angle of depression be x.
tan x=104.1/65
x=58.0 degrees
 
        
                    
             
        
        
        
Simplifying
15 + -5(4x + -7) = 50
Reorder the terms:
15 + -5(-7 + 4x) = 50
15 + (-7 * -5 + 4x * -5) = 50
15 + (35 + -20x) = 50
Combine like terms: 15 + 35 = 50
50 + -20x = 50
Add '-50' to each side of the equation.
50 + -50 + -20x = 50 + -50
Combine like terms: 50 + -50 = 0
0 + -20x = 50 + -50
-20x = 50 + -50
Combine like terms: 50 + -50 = 0
-20x = 0
Solving
-20x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-20'.
x = 0.0
Simplifying
x = 0.0
