Point o is the incenter of triangle abc. what is m

Step-by-step explanation:

we know that

The incenter of a triangle is the meeting point of the three angle bisectors of a triangle.

so

we have

-----> given problem

so

Remember that

In a triangle the sum of the internal angles must be equal to

so

In the right triangle OQB

substitute

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
