From a point on the ground 300 feet from the base of a factory, the angle of elevation of the top of the factory is 38 degre, and the angle
of elevation of the top of the smokestack is 52 degree. Find the height of
the smokestack to the nearest foot.

a negative exponent is translated as follows:

so, we have

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
