Which measurement is the most precise? a) 29 cm b) 28.8 cm c) 28.76 cm d) 28.762 cm

The answer is "It depends"

Step-by-step explanation:

All the possible options have different amount of digits after of the decimal point. If we have to decide the most precise measure, it will depend mostly on the way of using that value.

For example, if we are using a compass, we do not need a measure with decimal digits because it will be harder to draw with that instrument.

If we are using a 3D printer, it will be more precise to use a measure with decimal digits because the machine will be able to use that value to build something.

Finally, the answer will depend on the using of the value.

triangle abc is reflected on the line x=-6.5 then reflected again on the x axis

step-by-step explanation:

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
