Common Core Connection for 4th Grade Recognize that angles are formed when two rays share a common endpoint. Understand concepts of angle measurement. Measure angles in whole-number degrees using a protractor. WebSolution: One of the properties of lines and angles states that the sum of the adjacent linear angles formed by a line is 180°. Therefore, 4x + 2x = 180°. 6x = 180°. x = 180°/6 = 30°. We get the value of x as 30°. Hence, the first angle AOB is 4x = 4 × 30 = 120°. The other angle COB is 2x = 2 × 30 = 60°. rattlesnake\u0027s nz
