In triangle ABC, AB = 12. BC = 18, and m B = 75°. What are the approximate length of side AC and measure of $A? ОАПАС
20.3: m A = 58.99
ОВ.
AC
20.3: m XA = 34.8°
OC.
AC = 18.9: m LA
66.9°
OD
AC = 18.9; m A = 37.8°

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

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
