What is the size of the blue angle, and what do we call an angle with these measurements?

Answers:

The blue angle is 135 degrees

The angle is obtuse

Explanation:

Along the inner ring of values, the left arrow points at 135 (the midpoint of 130 and 140). Therefore, the blue angle is 135 degrees. Or you could note that starting at 130, and counting 5 spaces, will get you to 135. You could start at 140, and count down 5 spaces to get to the same spot.

Another way you can get the answer is to note that the blue arrow on the left is pointing at 45 along the top ring of numbers. This adds to 90 to get 90+45 = 135

Either way, you should get to 135 degrees as the angle value.

The angle is obtuse because the angle is larger than 90 degrees. It's wider or larger than a right angle.

there is no graph so i cant sorry
