Find the value of x in the isosceles triangle shown below.

x = √40

(Option B)

Step-by-step explanation:

Focus on one half of the triangle.

Base of half triangle

= 4÷2

= 2

Applying Pythagoras' Theorem,

x² = 6² +2²

x² = 40

x = √40

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
