Answer for brainliest! 40 points! i dont want to fail math.

x = 15

x = 15

The answers should be the same because the triangles are similar.  The ratio of the sides are in the same proportion.

Step-by-step explanation:

a.  x              12

=

20               16

using cross products

x*16 = 20 * 12

16x = 240

divide by 16 on each side

16x/16 = 240/16

x = 15

b  x              6

=

20               8

using cross products

x * 8 = 6 * 20

8x = 120

divide each side by 8

8x/8 = 120/8

x = 15

c.  The answers should be the same because the triangles are similar.  The ratio of the sides are in the same proportion.

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.
