Since Ryan is 5 feet tall, we will assume that the height of the cell-phone tower is x + 5. Since the given is 54 degrees. Tan 54degrees = x/80(feet) x=80(tan54) x=110 To finalize the answer, we will add up the height of the cell-phone tower to the answer. 110 + 5 = 115 feet So the answer to the question is that the height of the cell-phone tower is 115 ft.
59.4cm Use Pythagorean theorem to find the diagonal (^ means exponent) a^2 + b^2 = c^2 42^2 + 42^2= c^2 1764+1764=c^2 3528=c^2 square root both sides c= 59.39696962 round and you get 59.4 cm
