Answer:
0.45 cm
Step-by-step explanation:
Actual length of the micro chip
1988920000000000
1.98892 x 1000000000000000 (15 zeros)
The upper number (in this case 15) indicates the amount of zeros after the 1 (10 is 10^1, 100 is 10^2)
-12=4x-20
4x=12+20
4x=32
4 = 4
x=8
2.4
RSQ is a right anle triangle
tan(Q) = opposite/adjacent
tan(Ql = SR/QS
tan(Q = 12/5 = 2.4
