The vertices of AJKL have coordinates (5, 1), K(-2,-3), and L(-4,1). Under which transformation is AJ 'K'L'not congruent to AJKL?
A. A translation of two units to the right and two units down.
B. A counterclockwise rotation of 180 degrees around the origin.
C. A reflection over the x-axis.
D. A dilation with a scale factor of 2 and centered at the origin.

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

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
