River Avenue intersects Oak Street at a 55° angle. If Oak Street is parallel to Maple Street, which equation is true? Lines labeled Oak Street and Maple Street are parallel. A transversal labeled River Avenue cuts through both lines forming angles, from top left, going clockwise, blank, 55 degrees, blank, blank. With Maple Street, the angles are x degrees, blank, blank, blank. CLEAR CHECK x=55° x=90°−55° x=90°+55° x=180°−55°

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?
