True or false as you increase the angle of a projectile the x-component vector also increase

That depends on what you're calling the 'x-component'.

As you increase the launch angle of a projectile, the vertical component
of its initial velocity increases, and the horizontal component of its initial
velocity decreases.

At the same time, the vertical component of its acceleration is a constant
9.8 m/s² throughout the event, while the horizontal component of its
acceleration is a constant zero.
