Atriangle is equilateral if, and only if, it has three congruent angles.
based on this statement, which of the following is true?
a triangle has three congruent angles, therefore the triangle is equilateral.
a triangle is equilateral, therefore the triangle has no congruent angles.
a triangle is equilateral, therefore it has exactly two congruent angles.
a triangle has three congruent sides, therefore the triangle is isosceles.

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?
