In Exercises 15-42, translate each argument into symbolic form. Then determine whether the argument is valid or invalid. You may use a truth table or, if, applicable, compare the argument’s symbolic form to a standard valid or invalid form. (You can ignore difference in past, present, and future tense.) If you tell me what I already understand, you do not enlarge my understanding. If you tell me something that I do not understand, then your remarks are unintelligible to me . ∴ Whatever you tell me does not enlarge my understanding or is unintelligible to me .

A boat is 15 ft away from a point perpendicular to the shoreline. A
person stands at a point down the shoreline so that a 65° angle
is formed between the closest point to the boat, the person, and
the boat. How far is the person from the boat? Round your
answer to the nearest tenth of a foot. Show your work.
