Question

estimate the given rotation within 10 degrees:
answer attempt 1 out of 3
estimated angle: □°

Explanation:

Step1: Analyze the position of the angle

The angle is in the first - quadrant. The positive \(x\) - axis to the positive \(y\) - axis is \(90^{\circ}\).

Step2: Estimate the proportion of the angle

The angle seems to be about \(\frac{2}{3}\) of the \(90^{\circ}\) from the \(x\) - axis to the \(y\) - axis. Calculate \(\frac{2}{3}\times90^{\circ}=60^{\circ}\) (a rough estimate within \(10\) degrees).

Answer:

\(60\)
