A) find the absolute values: |0|, |13 - 8|, and
|8 - 13|.
b) for which numbers a is - a positive? for which is
- |a| positive?
c) a student claims that a = -a is true only for
a = 0. explain why the student is wrong. what
misconception does the student have about -a?

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
