$\color{blue}{\approx 2 \text{ radians} \\\approx 1.2 \text{ radians}}$
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: $\color{blue}{2 \text{ radians} \\1.2 \text{ radians}}$
