Use the law of cosines to solve the following problem. The robot arm shown in the figure places packages on a 2.25 m 1.25 m conveyer belt. What is the distance x? 100.0 Belt Determine the expression that can be evaluated to find x. O A. x= 2.252 + 1.252 - 2(2.25)(1.25) cos (100.0) O B. x= 2.252 + 1.252 + 2(2.25)(1.25) cos (100.0) O C. x=2.252 + 1.252 - (2.25)(1.25) cos (100.0) D. x= 2.252 + 1.252 -2(2.25)(1.25) cos (100.0) What is the value of x? X= (Type an integer or decimal rounded to two decimal places as needed.)Andrea and Carlos left the airport at the same time. Andrea flew at 170 mph on a course with a bearing of 80, and Carlos flewr at 240 mph on a course with a bearing of 210. How far apart were they after 6 hours? I: miles (Round to the nearest tenth.) Determine the length of a chord intercepted by a central angle of 17 in a circle with a radius of 40 centimeters. The chord length is approximately centimeters. (Round to the nearest tenth as needed.)
