The line that is diagonal means that it will have a degree measure of 180( aka a straight diagonal line) therefore if you subtract 124 from 180, you will get angle z which is 56
What you must do for this case is subtract both quantities and verify the final result. We have then: 15 3 / 10-13 9/10 = Rewriting 15.3 - 13.9 = 1.4 = 1 4/10 answer: this month fell 1 4/10 more centimeters of rain
