Assign point_dist with the distance between point (x1, y1) and point (x2, y2). The calculation is: Distance = SquareRootOf( (x2 - x1)2 + (y2 - y1)2 ). Sample output for the given program:

Points distance: 3.0

Code:

```
import math
x1 = 1.0
y1 = 2.0
x2 = 1.0
y2 = 5.0
point_dist = 0.0
result
print('Points distance:', point_dist)
```

2nd question Simple geometry can compute the height of an object from the the object's shadow length and shadow angle using the formula: tan(angleElevation) = treeHeight / shadowLength. Given the shadow length and angle of elevation, compute the tree height. Sample output for the given program:

Tree height: 13.5372315838

Code:

```
import math
angle_elev = 3.8
shadow_len = 17.5
tree_height = 0.0
'''Your solution goes here'''
print('Tree height:', tree_height)
```
