Answer:
m∠BXC = 30°
Step-by-step explanation:
The symbol ∠ means "angle", so "angle ∠BXC" is actually redundant. The "greater than" symbol is "<", which sometimes is used when the proper angle symbol is not available.
Here, the question is simply asking for the measure of angle BXC.
Ray BX crosses the outer, inner scales of the protractor at 40, 140. Ray CX crosses those scales at 70, 110. The measure of angle BXC in degrees is the difference between the numbers on the same scale:
70 -40 = 30 . . . using outer scale numbers
140 -110 = 30 . . . using inner scale numbers
The measure of angle BXC is 30°.
