so,
angle DAB = 25° + 35°
= 60°
now,
angle DAB + angle ADC. = 180°
or, 60° + ADC = 180°
or, ADC = 180° - 60°
Therefore, ADC = 120°
therefore, the angles of the PARALLELOGRAM are 60° and 120°.
Answer:
6.10×10² μK/ms
Step-by-step explanation:
When there are trailing zeros in a whole number, the number of significant figures is ambiguous. The given number would ordinarily be considered to have 2 significant figures, as the trailing zero would not count. In order to unambiguously specify the significant figures when there are trailing zeros, the number must be written as a decimal fraction or using scientific notation.
Here, we have 610 mK/s = 0.610 K/s = 610 μK/ms. The latter number can only be shown as having 3 significant digits if it is written in scientific notation:
6.10×10² μK/ms
Answer:
3m - 25
Step-by-step explanation:
3m - 25 will represent how many minutes she practiced this week:
3m represents 3 times the number of minutes she practiced last week. Then, subtract 25 from this.
This will represent 25 minutes less than 3 times the number of minutes she practiced last week.
The range is the set of the second values in the oredered pairs)
so Its c.
