Answer:

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 + ([tex]\frac{x²}{4}[/tex]

or 15² - 12² = [tex]\frac{x²}{4}[/tex]

or 225 - 144 = [tex]\frac{x²}{4}[/tex]

or 81×4 = x²

or x= [tex]\sqrt{324}[/tex]

i.e X= 18      Answer
