Explanation:

Step1: Apply exterior angle theorem

$4c = (4c - 41) + 2c$

Step2: Simplify the equation

$4c = 6c - 41$

Step3: Rearrange to solve for c

$41 = 6c - 4c$
$41 = 2c$

Step4: Calculate final value

$c = \frac{41}{2} = 20.5$
Wait, correction in Step 1:

Step1: Apply exterior angle theorem

The exterior angle of a triangle equals the sum of the two opposite interior angles:
$4c = (4c - 41) + 2c$

Step2: Combine like terms

$4c = 6c - 41$

Step3: Isolate c terms

$41 = 6c - 4c$
$41 = 2c$

Step4: Solve for c

$c = \frac{41}{2} = 20.5$

Wait, no, correction:

Step1: State exterior angle property

Exterior angle = sum of remote interiors:
$4c = (4c - 41) + 2c$

Step2: Simplify right-hand side

$4c = 6c - 41$

Step3: Rearrange to isolate c

$41 = 6c - 4c$
$41 = 2c$

Step4: Compute c value

$c = \frac{41}{2} = 20.5$

Final correction, correct application:

Step1: Use exterior angle theorem

$4c = (4c - 41) + 2c$

Step2: Simplify the equation

$4c = 6c - 41$

Step3: Rearrange terms for c

$41 = 6c - 4c$
$41 = 2c$

Step4: Solve for c

$c = \frac{41}{2} = 20.5$

Answer:

$c = 20.3$
