Kapil is programming a robot to always know its distance from its charging base by following these steps:
$\qquad \text{Step }1)$ Save $b$, which is the current distance from the base.
$\qquad \text{Step 2})$ Face charging base and turn $\theta^\circ$ to the right.
$\qquad \text{Step 3)}$ Move $x$.
$\qquad \text{Step 4)}$ Compute new distance from the base.
$\qquad \text{Step 5)}$ Go back to step $1$.
For example, it might happen that when the robot gets to step $4$ in its program,
$\qquad b = 70$ units,
$\qquad \theta = 60^\circ$, and
$\qquad x = 50$ units.
**In the example above, what would the robot's new distance from its base be?**
*Do not round during your calculations. Round your final answer to the nearest unit.*
