If BD= BC ,BD=5x-26, BC=2x+1, and AC=43, find AB ?

trasher [3.6K]

Answer:

Explanation:

here,

BD=BC

BD=5x-26

BC=2x+1

AC=43

AB=?

now,

BD=BC

or, 5x-26=2x+1

or, 5x-2x=1+26

or, 3x=27

or, x=9

replacing x,

BC=2x+1

=2*9+1

=19

then,

AC=AB+BC

or, 43= AB+19

or, 43-19=AB

or, 24=AB

True or false, permafrost grows in D climate regions<br> prove your answer

earnstyle [38]
