Answer:
x = 13.5
Step-by-step explanation:
We know that base angles of an isosceles triangle are equal. The base angles of the triangle are (4x)° each. The vertex angle of the traingle is (6x-9)°. So according to angle sum property of triangle,
![6x - 9 + 4x + 4x = 180](https://tex.z-dn.net/?f=6x%20-%209%20%2B%204x%20%2B%204x%20%3D%20180)
![= > 6x - 9 + 8x = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%206x%20-%209%20%2B%208x%20%3D%20180)
![= > 14x - 9 = 180](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2014x%20-%209%20%3D%20180)
![= > 14x = 180 + 9 = 189](https://tex.z-dn.net/?f=%20%3D%20%20%3E%2014x%20%3D%20180%20%20%2B%209%20%3D%20189)
![= > x = \frac{189}{14} = 13.5](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20x%20%3D%20%20%5Cfrac%7B189%7D%7B14%7D%20%20%3D%2013.5)
