Step-by-step explanation:
Since ZD is the median of TRAP, it bisects side TR, which means TR = 2ZD.
Using this information and the given values, we can set up an equation:
TR = 3x + 3 = 2ZD = 2(4x + 2) = 8x + 4
Simplifying this equation, we get:
3x + 3 = 8x + 4
Subtracting 3x from both sides, we get:
3 = 5x + 4
Subtracting 4 from both sides, we get:
-1 = 5x
Dividing both sides by 5, we get:
x = -1/5
Therefore, the value of x is -1/5.
