Answer:
m∠BXF = 140°
Step-by-step explanation:
The symbol "<" is "greater than." The symbol "∠" is "angle." When used as "m∠", it refers to "the measure of angle ...".
Here, you're asked for the measure of angle BXF.
You can see that it is an obtuse angle, so will have a measure greater than 90°. The protractor has two scales: one measuring angles counterclockwise, and the other measuring angles clockwise. Ray XF is aligned with the 0 on the inner (counterclockwise) scale, so the angle measure is found where ray XB crosses that scale.
Ray XB crosses the inner scale of the protractor at 140, so ...
m∠BXF = 140°.
