Kapil is programming a robot to always know its distance from its charging base by following these steps:
Step 1) Save b, which is the current distance from the base.
Step 2) Face charging base and turn 0° to the right.
Step 3) Move .
Step 4) Compute new distance from the base.
Step 5) Go back to step 1.
For example, it might happen that when the robot gets to step 4 in its program,
b = 70 units,
0 = 60°, and
z = 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.
