Answer:

x= 60° degree

Step-by-step explanation:

180°-40°= 140°

140= x+ x+ 20

140 -20 =2x

2x = 140 - 20

2x = 120

x = 60°

stepan [7]

Answer:

x= -19

y= -14

Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centim
Mandarinka [93]

The lower bound of the measurement is 65.5 millimetres.

A centimetre equals 10 millimetres, a measure is expressed by the <em>measured</em> magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:

y = x + \epsilon (1)

Where:

  • x - Measured magnitude, in millimeters.
  • y - Possible magnitude, in millimeters.
  • \epsilon - Uncertainty, in millimeters.

If we know that y = 67.5\,mm and \epsilon = 1\,mm, then the lower bound of the measurement is:

y = 67.5\,mm - 2\cdot (1\,mm)

y = 65.5\,mm

The lower bound of the measurement is 65.5 millimeters.
