Examine the diagram. It is not drawn to scale.

A triangle has angles 28 degrees, A, C. The exterior angle to the angle with a measure of 28 degrees is D, the exterior angle to angle A is B, the exterior angle to angle C is 125 degrees.

Choose the equation that cannot be used to find the measure of angle B.

m∠B = m∠C + 28°.

m∠B = 360° – (m∠D + 125°).

m∠B = 180° – m∠A.

m∠B = m∠D + 125°.

Graph the equation. select integers for x

Billy plotted −3 4 and −1 4 on a number line to determine that −3 4 is smaller than −1 4 .is he correct? explain why or why not

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?
