How can I exclude a range of values when generating random numbers?

Currently im making a pong game. The main problem is that there is a chance
that the ball will launch at an angle of ±90 degrees, and I would like to make it lauch at all angles,
but, for example, exclude the range from 70 to 110 degrees. I have no idea how to do it.

Here is my code

private void Launch()
    float minAngle = 0;
    float maxAngle = 180;

    float angle = Random.Range(minAngle, maxAngle);
    float radians = angle * Mathf.Deg2Rad;
    float xSpeed = Mathf.Cos(radians) * BaseSpeed;
    float ySpeed = Mathf.Sin(radians) * BaseSpeed;
    _ballInstance.velocity = new Vector2(xSpeed,ySpeed);
