Which equation can you use to solve for x? x + 56 = 180 x + 146 = 180 180−x=146 x + 56 = 146 the figure contains a pair intersecting lines. one of the four angles formed by the intersecting lines is labeled 146 degrees. the angle opposite and not adjacent to this angle is broken into two smaller angles by a ray that extends from the point where the two lines intersect. one of these smaller angles is labeled 58 degrees, and the other smaller angle is labeled x degrees.

In new york city at the spring equinox there are 12 hours 8 minutes of daylight. the longest and shortest days of the year very by two hours and 53 minutes from the equinox in this year the equinox falls on march 21 in this task you use trigonometric function to model the hours of daylight hours on certain days of the year in new york city a.what is the independent and dependent variables? b.find the amplitude and the period of the function. c.create a trigonometric function that describes the hours of sunlight for each day of the year. d. graph the function you build in part c. e. use the function you build in part c to find out how many fewer daylight hours february 10 will have than march 21. you may look at the calendar.
