it is 90. it is 90.
7.8 + 12 = 19.8
It is 12 degrees because 78+12 = 90 degrees
90-78= 12 degrees
90-78 = 12 degrees
90 - 12 = 78 is the complement180 - 12 = 168 is the supplement
90% of 78 = 90% * 78 = 0.9 * 78 = 70.2
Do-it-in-your-head method: 90 - 12 = 78; 78/2 = 39 which is your lower number, making the other number 51. Shazam!
