- Belts and Pulleys A thin belt of length L surrounds two pulleys of radii R and r, as shown in the figure (1). aShow that the angle in rad where the belt crosses itself satisfies the equation +2cot2=LR+r Hint: Express L in terms of R, r, and by adding up the lengths of the curved and straight parts of the belt. bSuppose that R=2.42ft, r=1.21ft, and L=27.78ft. Find by solving the equation in part a graphically. Express your answer both in radians and in degrees.

Here is a way to estimate the distance When the moon is seen at its zenith at a point A on the earth, it is observed to be at the horizon from point B see the following figure. Points A and B are 6155 mi apart, and the radius of the earth is 3960 mi. a Find the angle in degree. b Estimate the distance from point A to the moon.arrow_forwardComparing a Triangle and a Sector of a Circle Two wood sticks and a metal rod, each of length, are connected to form a triangle with angle 1 at the point P, as shown in the first figure below. The rod is then bent to form an arc of a circle with center P, resulting in a smaller angle 2 at the point P, as shown in the second figure. Find 1, 2 and 12arrow_forward
- CONCEPTS If the angle is in standard position and P(x,y) is a point on the terminal side of , and r is the distance from the origin to P, then sin= cos= tan=arrow_forwardLength of a Guy Wire A communications tower is located at the top of a steep hill, as shown. The angle of inclination of the hills is 58. A guy wire is to be attached to the top of the tower and to the ground, 100 m downhill from the base of the tower. The angle in the figure is determined to be 12. Find the length of the cable required for the guy wire.arrow_forwardGeometry 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_forward
