In ΔEFG, EG is extended through point G to point H, angle FGH = (4x-1) m∠FGH=(4x−1) ∘ , angle GEF = (x+18) m∠GEF=(x+18) ∘ , and angle EFG = (x-5) m∠EFG=(x−5) ∘ . Find angle GEF. M∠GEF.

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
