Answer
(multiple possible answers)
$-5.28$ radians
$7.28$ radians
$13.56$ radians
Work Step by Step
RECALL:
(i) The angles cotermnal with $\theta$ can be found using the formula $\theta_1=\theta + 2n\pi$, where $n$ is an integer
(ii) $\pi \approx 3.14$
Thus, using the formula in (i) above and using $\pi=3.14$, three angles that are coterminal with $1$ radian are:
(1) $1+2(1)(3.14) = 1+6.28=7.28$
(2) $1+2(-1)(3.14) = 1-6.28= -5.28$
(3) $1+2(2)(3.14) = 1+12.56=13.56$
