I don't know if this is the right one but i hope this helps. this is how i learned it. step 1=get variables on one side oof the equal sign by using inverse operation (add or subtract smaller variable) step 2= get constants away from variable to the other side of the equal sign by using inverse operations (add or subtract constant) step 3: isolate the variable using inverse operation (multiply or divide)
Okay, so this is just a bunch of random information that's eying to trick you. The answer is in the question. "the telephone pole to a point on the ground 40 feet from its base."
