What is the degree measure of the angle equal to: 7/10 of the unfolded angle

What is the degree measure of the angle equal to: 7/10 of the unfolded angle, 11/18 of the unfolded angle, 8/9 of the right angle, 13/10 of the right angle?

a) An unfolded angle is an angle whose rays form a straight line. The degree measure of the unfolded angle is 180 °.

1) To find 7/10 of the unfolded angle, we use the rule: To find the fraction of a number (in this case, 7/10 of 180 °), you need to multiply the fraction by the number.

Then 7/10 of 180 = 7/10 * 180 = 7/1 * 18 = 126 °.

2) 11/18 from the unfolded angle: 11/18 * 180 = 11/1 * 10 = 110 °.

b) A straight angle is an angle whose degree measure is 90 °.

1) 8/9 right angle: 8/9 * 90 = 8/1 * 10 = 80 °.

2) 13/10 right angle: 13/10 * 180 = 13/1 * 18 = 234 °.
