MAC 1114 Module Test 8 Name___________________________________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Solve the triangle, if possible. 1) B = 75.7° b = 5.99 a = 20.6 A) A = 37.85°, C = 66.45°, c = 26.59 B) A = 38.85°, C = 66.45°, c = 30.59 C) A = 36.85°, C = 66.45°, c = 28.59 D) No solution Answer: D Objective: (7.1) Solve Triangle (AAS) Determine whether there is sufficient information for solving a triangle, with the given combination of angles and sides, by the law of sines. 2) B, a, and c A) No B) Yes Answer: A Objective: (7.1) Determine if Sufficient Information is Provided Find the area of triangle ABC with the given parts. 3) A = 30.0° b = 13.9 in. c = 8.7 in. Objective: (7.1) Find Area of Triangle Solve the problem. 4) In aerial photography, ground coordinates (X, Y) in feet are given by X = (a - h)x f sec θ - y sin θ , Y = (a - h)y cos θ f sec θ - y sin θ , where a is the altitude in feet of the airplane, h is the elevation in feet of the object, f is the length of the camera in inches, θ is the tilt angle of the camera, and (x, y) are the photographic coordinates. Find the ground coordinates of an object if a = 4500 ft, h = 690 ft, f = 12 inches, (x, y) = ( - 5.6, 1.6), and the photograph is taken vertically (i.e. with no tilt). Round your answers to the nearest tenth.
