None because the triangles have different lines
Answer:
x= -13/5
Step-by-step explanation:
Given that the distance between two lines in the measurement instrument is 0.01m, the maximum error should be 0.01m/2 = 0.005 m.
If you do a good work, the real measure is 1.20m +/- 0.005m, this is between 1.195 and 1.205.
There are only 2 perfect cubes in between 1000 and 2000.
11^3 = 1331
12^3 = 1728
