Protractor is a tool used to measure the angles.
Some of the protractors are half circle protractors to measure angles up to 180° and some of them are full circle protractors to measure angles up to 360°.
A. 105°
B. 75°
C. 180°
D. 130°
Correct Answer: A
Step 1: ∠XYZ is made up of two rays, YX and YZ, with the common endpoint Y.
Step 2: ∠XYZ is the measure between YX and YZ.
Step 3: On the protractor scale, YX is passing through 180° and YZ is passing through 75°.
Step 4: Difference = 180° - 75° = 105°
Step 5: The measure of ∠XYZ is 105°.
