30 minus 90 is negative 60, if I'm correct.
The compliment of an angle is found by taking 90 degrees minus the known angle. Therefore, you take 90 minus 30 which equals 60 degrees.
76 - 90 = -18 -18 - -48 = 30.
90 minus 30 percent - and therefore 30 percent OFF the number, is equal to 90 x (1 - (30 / 100)) = 90 x (1 - 0.3) = 90 x 0.7 = 63. 30 percent OF 90 is equal to 90 x (30 / 100) = 90 x 0.3 = 27
"What_is_the_complement_of_an_angle_that_measures_30_degrees"This guy was mean and its 90 minus 30. If you can't get that well . . .
90 - 90 = 0
-30 - (-24) = -30 + 24 = -6
90/5 = 1818/2 = 9
90 - 55 = 35
90 - 45 = 45
90 - 80 = 10
90 - 72 = 18
90 - 70 = 20
