Question

Janet is using the protractor to draw an angle. First, she draws ray ST.

Half-circle protractor with degree markings from 0 to 180. Points labeled S, T, V, W, X, and Z are marked on the edge of the protractor. Ray ST is drawn horizontally along the 0-degree line.

If Janet wants the angle to measure 50°, she should draw another ray that starts at point S and passes through —

To create an angle measuring 50° with ray ST as the baseline at the 0° line on the protractor, we need to identify the correct point that corresponds to this measurement based on the protractor's markings.

Since ray ST is horizontal along the 0-degree line, the other ray needs to extend upwards in the direction of the protractor's degree markings.

Here’s how to determine the right answer:

- **Point V**: This point is typically near the 0-degree mark and would not correspond to 50°.
- **Point W**: This point is usually around 40°, which is not what we want either since it's not 50°.
- **Point X**: This is generally closer to 50° on the protractor, likely the point we need.
- **Point Z**: This point is higher than 50°, likely around 60°.

Given this information, Janet should draw another ray that starts at point S and passes through **point X** to create a 50° angle.

So the correct response is:

**B. point X.**
