Benjamin is trying to find the height of a radio antenna on the roof of a local building. He stands at a horizontal distance of 25 meters from the building.
The angle of elevation from his eyes to the roof (point A) is 28°, and the
angle of elevation from his eyes to the top of the antenna (point B) is 40°. If
his eyes are 1.52 meters from the ground, find the height of the antenna (the
distance from point A to point B). Round your answer to the nearest meter if
necessary. A

When you answer this can you explain

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?
