a) 0
b) 70
c) 110

Explanation:

Question 8

An acute angle is less than 90 degrees, and an obtuse angle is greater than 90 degrees but less than 180 degrees. The angle between \( IH \) (vertical) and \( IJ \) is less than 90 degrees, so it's acute.

Step1: Identify the protractor scale.

The horizontal ray is at 0° (or 180°), and the other ray aligns with the 70° mark on the protractor (since it's between 0° and 90° - 180° scale, we use the inner or outer scale that makes sense; here, the angle from the horizontal (0°) to the blue ray is 70°).

Step2: Confirm the measure.

Looking at the protractor, the angle formed is 70 degrees.

Answer:

A) Acute
