Lisa draws several right triangles and measures the angles. her measurements are shown in the diagram. each right triangle has one right angle (90° angle) and two non-right angles (angles that are not 90° angles). what conjecture(s) could lisa make based on her exploration? select all that apply.

a. right triangles always have two equal sides.

b. the sum of the measures of the two non-right angles of a right triangle is 90°.

c. the sum of the measures of the three angles in a right triangle is 180°.

d. right triangle is always scalene.

e. the two non-right angles of a right triangle are both acute angles.

1jessica's home town is a mid-sized city experiencing a decline in population. the following graph models the estimated population if the decline continues at the same rate. select the most appropriate unit for the measure of time that the graph represents. a. years b. hours c. days d. weeks

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?
