*15 points help easy question*
Find the value of x in the isosceles triangle shown below.
X=square root of 135
X=12
X=6
X=square root of 54

x = 12

Step-by-step explanation:

The segment from the vertex to the base is a perpendicular bisector.

Using Pythagoras' identity on the right triangle on the right.

( x )² + 3² = ( )² , that is

x² + 9 = 45 ( subtract 9 from both sides )

x² = 36 ( multiply both sides by 4 )

x² = 144 ( take the square root of both sides )

x = = 12

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
