### Collision of Billiard Balls

**Scenario Description:**

One billiard ball is shot east at a speed of 1.9 m/s. A second, identical billiard ball is shot west at a speed of 0.90 m/s. The two balls undergo a glancing collision, meaning it is not a direct head-on collision. As a result of the collision, the second ball is deflected by 90° and moves north at a speed of 1.36 m/s.

**Question:**

**Part B**: Determine the direction of the first ball after the collision. Provide the direction as an angle measured south of east.

Express your answer with two significant figures and include the appropriate units.

**Input fields:**

- θ (angle) = [ Textbox for Value ]
- Units = [ Textbox for Units ]

**Submit Options:**

This setup poses a classic physics problem involving momentum and angle calculations following a collision.
