Question

1.a triangular pasture has sides of length 375 feet, 250 feet, and300 feet.calculate the area of the pasture

2. ambiguous case of the law of sines: two sides and an angle are given. Determine whether the given information results in one triangles, two triangles ,or no triganlge at all. clearly show how you use the law of sines. you do not need to solve the triangles.

a) a=3, b=7, A=70 degrees. b) a = 20, c= 30,B=40 degrees. c) a = 32, c= 16, A= 120 degrees.
