Question: 3. Math on the Spot Use a protractor to measure the following angles. A B A: An angle shape with one ray extending horizontally to the left and another ray extending upward slightly to the right from the same vertex; position_hint \in {top-left}. B: An angle shape with one ray extending upward-left and another ray extending upward-right from the same vertex; position_hint \in {top-right}.

1. **Stating the problem:** We need to measure two angles, A and B, using a protractor. 2. **Understanding angles:** An angle is formed by two rays with a common vertex. The measure of an angle is the amount of rotation from one ray to the other, measured in degrees. 3. **Angle A:** One ray extends horizontally to the left (which we consider as 180° on a protractor), and the other ray extends upward slightly to the right. This suggests an angle less than 90° but more than 0°. 4. **Using a protractor for angle A:** Place the center of the protractor at the vertex. Align the baseline with the horizontal ray pointing left (180° mark). The other ray points slightly upward to the right, so measure the angle between 180° and that ray. 5. **Estimate angle A:** Since the ray is slightly upward to the right, the angle is approximately $$30^\circ$$. 6. **Angle B:** One ray extends upward-left and the other upward-right from the same vertex. This forms an angle opening upwards. 7. **Using a protractor for angle B:** Place the center of the protractor at the vertex. Align one ray with the 0° mark and measure the angle to the other ray. 8. **Estimate angle B:** Since the rays are symmetric and open upwards, the angle is approximately $$60^\circ$$. **Final answers:** - Angle A is approximately $$30^\circ$$. - Angle B is approximately $$60^\circ$$.
