Question

Does anyone know it?

Answer 1

Answer:

4π/5

Step-by-step explanation:

APC angle is equals to AC arcle.

The inscribed angle is 2π/5. To discover an inscribed angle, the formula is:

IA = IC/2

IA = inscribed angle

IC = central angle

IA = 2π/5

$\frac{2\pi}{5} = \frac{IC}{2} \\\\\ 5IC = 4\pi \\\ IC = \frac{4\pi}{5}$

IC angle = AC arcle

AC = 4π/5
