Consider the regular dodecagon. A dodecagon has 12 sides and has a point at the center. Which statements are true regarding the regular dodecagon? Check all that apply. The smallest angle of rotational symmetry for the dodecagon is 30°. The dodecagon has a rotational symmetry of 180°. The order of rotational symmetry for the dodecagon is 10. The dodecagon has a rotational symmetry of 135°. The angles of rotational symmetry for the dodecagon are multiples of 30°.

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

a) 7x=7
