Two triangles each have an angle of measure x and an angle of measure y. Which statement about the measure of the remaining angles is true? A. The two angles are congruent. Their measure is x + y

B. The two angles are congruent. Their measure is (180 - x) + (180 - y)

C. The two angles are congruent. Their measure is 180 - x - y

D. The two angles are not necessarily congruent. Their measures could be different

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?
