Jed used a protractor to draw an angle measuring 72°. He asked Mark to draw an angle that would be complementary to his angle. What should the measure of Mark's angle be? A.
144°
B.
18°
C.
108°
D.
162°

B

Step-by-step explanation:

Complementary angles are 2 angles that add up to 90 degrees.

If the first angle is 72 degrees, then subtract 90 - 72 to get the measure of the second angle.

90 - 72 = 18

= 18 degrees

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
