Answer
$\color{blue}{\approx 2 \text{ radians}
\\\approx 1.2 \text{ radians}}$
Work Step by Step
To approximate the angle whose sine value is $-0.95$, look up in the given figure the angle/s whose terminal side crosses the unit circle along the line $y=-0.95$.
Notice that the angles $2$ radians and $1.2$ radians cross the unit circle along the line $y=-0.95$.
Thus, the angles are approximately:
$\color{blue}{2 \text{ radians}
\\1.2 \text{ radians}}$
