The value of x is 3.
Solution:
In the given triangle, a = 4, b = 3, x = ? and y = 2.25.
To find the value of x:
The image of the formula is attached below.
Angle bisector theorem:
An angle bisector of a triangle divides the interior angle's opposite side into two segments that are proportional to the other two sides of the triangle.

Do cross multiplication.
9 = 3x
Divide by 3 on both sides,
3 = x
Switch the sides.
x = 3
The value of x is 3.
