Which statement is true about angles 1 and 2? O They are congruent.
O They are right angles.
O They are complementary.
O They are supplementary.

the correct one is C or the angles are complementary

Step-by-step explanation:

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

the answer is a i belaeve atleast thats what my calculator just gfave me
