What is the measurement of this angle?

140°

Step-by-step explanation:

The tool that the image is showing is a protractor. A protractor helps measure angles.To find the value of the angle you're measuring, look at the small numbers going around the protractor.The measure of the angle will be the number that shows under the other line. Since there are 2 numbers, remember this:If the flat line is on the left, use the number on top. If the flat line is on the right, use the bottom.Since this angle's flat part is on the left, use the top number for the measure. The measure is 140°.
