Solve the triangle. a = 16, b = 20, c =12 O (Round to one decimal place as needed. ) O (Round to one decimal place as needed. ) (Round to one decimal place as needed.)Solve the following triangle using either the Law of Sines or the Law of Cosines. B = 28', C = 58, a=8 Select the correct choice below and, if necessary, fill in the answer boxes to complete your choice. (Round side lengths to the nearest hundredth and angle measures to the nearest degree as needed.) O A. There is only one possible solution for the triangle. The measurements for the remaining angle A and sides b and c are as follows. CA O B. There are two possible solutions for the triangle. The measurements for the solution with the smaller angle A are as follows. The measurements for the solution with the larger angle A are as follows. O C. There are no possible solutions for this triangle.Solve the following triangle. 300 120 B 7 O (Simplify your answer.) (Type an integer or decimal rounded to two decimal places as needed.) (Type an integer or decimal rounded to two decimal places as needed.)Use the right triangle and the given information to solve the triangle. 1) a=4; E5255\"; find b. c, and A. b = D [Round to the nearest hundredth as needed.) c = D {Round to the nearest hundredth as needed.) A: D {Round to the nearest tenth as needed.) A state trooper is hidden 30 feet from a highway. One second after a truck passes, the angle 0 between the highway and the line of observation from the patrol car to the truck is measured. See the 1 sec illustration. Complete parts (a)-(c). 1 30 ft (a) If the angle measures 17, how fast is the truck traveling? Express the answer in feet per second and in miles per hour. If the angle measures 17, the speed of the truck is feet per second. (Do not round until the final answer. Then round to two decimal places as needed.) If the angle measures 17, the speed of the truck is miles per hour. (Use the answer from part (a) to find this answer. Round to one decimal place as needed.) (b) If the angle measures 21", how fast is the truck traveling? Express the answer in feet per second and in miles per hour. If the angle measures 21, the speed of the truck is feet per second. (Do not round until the final answer. Then round to two decimal places as needed.) If the angle measures 21, the speed of the truck is miles per hour. (Use the answer from part (b) to find this answer. Round to one decimal place as needed.)(-2] It the speed limit is 55 miles per hour and a speeding ticket is issued for speeds at 5 miles per hour or mere ever the limit: for what angles should the trooper issue a ticket? The trppper should issue a ticket when the angle is equal to or less than D\". [Round to the nearest tenth as needed.)
