WebOct 6, 2024 · For problems in which we use the Law of sines given one angle and two sides, there may be one possible triangle, two possible triangles or no possible triangles. There are six different scenarios related to the ambiguous case of the Law of sines: three result in one triangle, one results in two triangles and two result in no triangle. WebNov 17, 2024 · Another way of stating the Law of Sines is: The sides of a triangle are proportional to the sines of their opposite angles. Proof To prove the Law of Sines, let ABC be an oblique triangle. Then ∠ABC can be acute, as in Figure 2.1.1 (a), or it can be obtuse, as in Figure 2.1.1 (b).
WebWhen you write and solve the law of sines, you end up with sinC=0.32 or something. You type sin^-1 (0.32) in your calculator and you are given an acute angle. Actually there are two solutions to the equation sinC=0.32. One is acute (your calculator gave it to you) and the other solution is obtuse.
