Round to estimate the quotient then solve
2,970 divided by 11
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
the correct option is 2.
step-by-step explanation:
according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.
it is given that triangles abd, cad, and cba are similar.
two triangles are similar if their corresponding sides are proportional.
in triangle cba, using pythagoras theorem
)
triangle abd and cba are similar,
(2)
triangle cad and cba are similar,
)
using (1), (2) and (3), we get
hence proved.
therefore option 2 is correct.
