- A 20 meter line is used to tether a helium-filled balloon. The line makes an angle of approximately 85 with the ground because of a breeze. (a) Draw a right triangle that gives a visual representation of the problem. Label the known quantities of the triangle and use a variable to represent the height of the balloon. (b) Use a trigonometric function to write and solve an equation for the height of the balloon. (c) The breeze becomes stronger and the angle the line makes with the ground decreases. How does this affect the triangle you drew in part a? (d) Complete the table, which shows the heights (in meters) of the balloon for decreasing angle measures .

- Refraction When you stand in shallow water and look at an object below the surface of the water, the object will look farther away from you than it really is. This is because when light rays pass between air and water, the water refracts, or bends, the light rays. The index of refraction for water is 1.333. This is the ratio of the sine of 1 and the sine of 2 (see figure).

A graph of the data is given in Figure 19, where we have used d to represent the day (with d = 1 corresponding to January 1) and h the number of hours of daylight. Find the equation of a trigonometric function to use as a model for these data.arrow_forwardTake this test as you would take a test in class. When you are finished, check your work against the answers given in the back of the book. Consider an angle that measures 54 radians. (a) Sketch the angle in standard position. (b) Determine two coterminal angles (one positive and one negative). (c) Convert the radian measure to degree measure.arrow_forward
- Geometry Use a compass to sketch a quarter of a circle of radius 10 centimeters. Using a protractor, construct an angle of 20 in standard position (see figure). Drop a perpendicular line from the point of intersection of the terminal side of the angle and the arc of the circle. By actual measurement, calculate the coordinates x,y of the point of intersection and use these measurements to approximate the six trigonometric functions of a 20 angle.arrow_forwardFor each angle, sketch a right triangle. Label the sides of the triangles +or . Determine the reference angles and functions of the angles. Determine the sine, cosine, tangent, cotangent, secant, and cosecant functions for each of these angles. Round the answers to 4 decimal places. 207arrow_forward
