He equation cos (35 degree) equals StartFraction a Over 25 EndFraction can be used to find the length of Line segment B C.

Triangle A B C is shown. Angle A C B is a right angle and angle C B A is 35 degrees. The length of C B is a and the length of hypotenuse A B is 25 inches.

What is the length of Line segment B C? Round to the nearest tenth.

14.3 in.
20.5 in.
21.3 in.
22.6 in.

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
