Figure A is a scale image of figure B

What is the value of X

x = 5.4

Step-by-step explanation:

Since A is the scale image of B,

4/3 = 7.2/x

Cross multiplying,

4x = 3*7.2

Dividing by4,

x = 3*7.2 / 4

x = 5.4

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
