Don't waste your points, it says the number on the protractor, whatever number the red line goes through is the angle and for the matching one, 90 is always the center as its exactly half of 180, so anyone less than that is acute and greater is obtuse, these questions give you the answer.
Answer:
D) 140
Explanation:
To find 140 degrees on a protractor, first locate the zero mark or starting point on the protractor. This is typically a small dot or a straight line near the center of the protractor.
Then, moving clockwise from the zero mark, locate the first line or tick mark on the outer edge of the protractor that is labeled as 10 degrees.
Continue moving clockwise and locate the line or tick mark that is labeled as 140 degrees. This line or tick mark will be located between the 130 degree mark and the 150 degree mark on the outer edge of the protractor.
To use the protractor to measure an angle of 140 degrees, place the center point of the protractor at the vertex of the angle and align the baseline of the protractor with one side of the angle. Then, read the measurement at the other side of the angle, which should align with the line or tick mark labeled as 140 degrees.
