. Given ABCD 2 EFGH, what is the value of X? H Н 6 m 7 m 5 m А D 9 m

Nookie1986 [14]

Answer:

x=6 cm

Step-by-step explanation:

As given in the question that ABCD is congruent to EFGH.

We can say that,

AD <-----> EH {Corresponding Parts Of Congruent Polygons}

AD=EH

We are given that,

$AD=9\\EH=(2x-3)\\Hence,\\As\ AD=EH\\9=2x-3\\9+3=2x\\12=2x\\x=6$

Answer:

x = 4

Step-by-step explanation:

To solve, simplify the expression then use inverse operations to isolate x.

$x - 4 = 0^2\\x-4 = 0\\x-4+4=0+4\\x = 4$
