Find the value of X in the Isosceles triangle shown below

D

Step-by-step explanation:

Consider the right triangle on the right with base = x

Using Pythagoras' identity

The square on the hypotenuse is equal to the sun of the squares on the other 2 sides, that is

( x )² + 12² = 13², that is

x² + 144 = 169 ( subtract 144 from both sides )

x² = 25

Multiply both sides by 4

x² = 100 ( take the square root of both sides )

x = = 10 → D

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
