A chord is an example of a secant. 1. In the diagram, which rays are secants? Which segments are secants? D B C E 2. Fatima is asked to find the value of x. She says erit of inspristal that the angle measure is the average of the intercepted arc measures, or half the sum of the intercepted arc measures, so the value of x is 55. Is Fatima correct? If not, correct her error. X = 90 + 20 2 = 55 90° 20° 3. Find the value of each variable. a. 290 307 303 b.
