ABCD is a parallelogram. If m∠CDA = 79, then m∠ABC = ?

ABC=79°

Step-by-step explanation:

Reason is Alternate Angle

ABC=79°

Step-by-step explanation:

angle ABC and CDA alternate

therefore alternate angles are equal

Angle ABC =CDA is 79°

if you explain the the question more correctly i might be able to answer this better

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
