Explanation:
The two digit formed by tens and ones is the complement of an 18 degree angle. To find the compliment of an angle, subtract the angle from 90 degrees. 90-18=72
72
Hundreds is increased by 6 to 15. H+6=15 -----> H=15-6 --->H=9
9
The largest prime less than 20 is 19. So, Thousands Place(T) plus Hundreds place(9) plus Tens place(7) plus Ones place(2) equals 19
T+9+7+2=19 Just subtract---->T=19-9=10 10-7=3 3-2=1 T=t
