Answer 2

X = 18

Step-by-step explanation

The shown figure of isosceles triangle can be drawn as :

Now it become a right angle triangle

From right angle triangle rule

hypotenuse² = Perpendicular² + Base²

i.e 15² = 12² + (
`(x²)/(4)`

or 15² - 12² =
`(x²)/(4)`

or 225 - 144 =
`(x²)/(4)`

or 81×4 = x²

or x=
`√(324)`

i.e X= 18 Answer
