16. in the diagram below. abc and ade are similar. if ab -6, bd-4, and bc-7, then what is de

The measure of the side DE is   unit  .

Step-by-step explanation:

Given as Δ ABC  and  Δ ADE are similar :

The measure of side AB = 6  unit

The measure of side BD = 4  unit

The measure of side BC = 7  unit

Let The measure of side DE = x  unit

From The property of similar triangle

=

or. =

or, . =

Or,   =

or, 3 × x = 7

∴  x =

Hence the measure of the side DE is   unit  . answer

glide reflection.

its mainly because the pattern will be infinite and will never end. it will look like a gilder or like a filpbook when set to motion.

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
