Question

click and drag the yellow circle in a counterclockwise direction to create a 125° angle to within 10°. 90° 135° 45° 180° 0°

Explanation:

Step1: Identify the target - angle range

The target angle is $125^{\circ}$ within $10^{\circ}$. So the acceptable range is from $125 - 10=115^{\circ}$ to $125 + 10 = 135^{\circ}$.

Step2: Analyze the given reference angles

We have reference angles of $90^{\circ}$, $135^{\circ}$, $180^{\circ}$ and $45^{\circ}$. We need to drag the yellow - circle to an angle within the $115^{\circ}-135^{\circ}$ range. Since $135^{\circ}$ is the upper - bound of our range, we should drag the circle close to the $135^{\circ}$ mark but slightly less than it to be within the range.

Answer:

Drag the yellow circle to an angle between $115^{\circ}$ and $135^{\circ}$, closer to $135^{\circ}$.
