Answer:
D. Pawnbroker
Step-by-step explanation:
x = 40
If you add the total of 3 angles in a STRAIGHT line, you have to get 180 in total.
So, x = 180 - ( 80 + 60 )
= 180 - 140
= 40
21.0.26
22. 0.9
23.0.30
80% = 0.8
100% = 1
0.8 = 72
1 = x
0.8* x = 72 * 1
x = 72 / 0.8 = 90
0.8 * 90 = 72
80% * 90 = 72
