What is the measure of angle k?

63

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

6x-9 + 4x+7 = 118

Combine like terms

10x -2 =118

Add 2 to each side

10x = 120

Divide by 10

10x/10 =120/10

x = 12

We want to find angle k

k = 6x-9

  = 6*12 -9

   = 72 -9

   =63

The exterior angle is equal to the sum of opposite interior angles.

i dont know

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
