Answer: A. Acute; 35°
Step-by-step explanation:
When we use to find an angle with a protector then we follow the following steps,
Step 1) First place the midpoint of the protractor on the vertex of the angle.
Step 2) Line up one side of the angle with the zero line of the protractor.
Step 3) Read the degrees where the other side crosses the number scale.
Here the vertex of the angle is O which is covered by the 0 of the number line of the protector,
Also, the other side OC of the angle is crossed the number scale at 35.
Thus, m∠ AOC = 35°
Which is an acute angle,
⇒ Option 1 is correct.
