# Chapter 4 - Section 4.1 - Angles and Radian Measure - Exercise Set - Page 533: 93

$2radians,114.59^{\circ}$

#### Work Step by Step

We know that $\theta=\frac{s}{r}$ We plug in the known values to obtain: $\theta=\frac{8000}{4000}=2radians$ Now we can convert this angle into degrees as $\theta=2\times \frac{180^{\circ}}{\pi}=114.59^{\circ}$
