4. The height of a radio tower is to be measured by measuring both the horizontal distance X from the center of its base to a measuring instrument and the vertical angle of the measuring device (see the following figure). If five measurements of the distance L give (in feet) values 150.42, 150.45, 150.49, 150.52, 150.40 and four measurements of the angle θ give (in degrees) values 40.26, 40.27, 40.29, 40.26 estimate the height of the tower.
