Use the triangle sum theorem to find the missing problem: suppose you want to make a triangular rack to go along with your new pool table. the rack will be an equilateral triangle with sides that are 38 cm long. if you have 120 centimeters of wood already, would you need to buy more wood before beginning the project? explain your answer

the f

last graph i believe

step-by-step explanation:

worked it out i believe

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
