state what additional information is required in order to know that the triangles are congruent for the reason given.

To me, it looks like it should already be eligible for SAS.

Step-by-step explanation:

SAS stands for Side, Angle, Side (what items have to be congruent for this method to work.)

As we look at the picture,  there are two sides equal, and an angle between them.

So, it looks like SAS is already viable to use, without having to add more information! (at least from what I can say.)

Sorry about my poor answer, I'm in a Zoom Class right now.

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.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
