To find the height of a pole, a surveyor moves 120 feet away from the base of the pole and then, with a transit 8 feet tall, measures the angle of elevation to the top of the pole to be 26. to the nearest foot, what is the height of the pole

Refer to the figure.
Let AB be the height of the pole; CD be the height of the transit; BC is the distance from the base of the pole to the transit.

Triangle ADE is a right triangle with angle D measuring 26 degrees. Using the tangent function, we have
     
So, 
     
     

Therefore, the overall height of the pole is 
     

The height of the pole is 66.53 feet. 

17.48 lbs on Mars
108.65 lbs on Jupiter

So subtract 
108.65
-  17.48
