A set of Mathis is normally distributed with a mean of 81 and a standard deviation of 5. If Adams z-score was -0.6 and Leah’s z-score was 2.2, How many points higher did Leah score than atom

40 degrees

Step-by-step explanation:

The answer is 40 degrees. Angle x and angle y form vertical angles, therefore x = y. Angle y forms a straight line with the 80° angle and the 60° angle which means that 80° + 60° + y = 180°. 140° + y = 180°. y= 180° - 140°. y = 40°. As mentioned earlier: x = y, so x = y = 40°.

Hope this helps
