What is the maximum number of distinct triangles that can be formed if m<A = 30, b = 8, and a = 5 (1) 1 (3) 3 (2) 2 (4) 0 Can I use law of sines to answer such questions about how many different triangles?

Hello Magentarita, Let's look at both cases: Recall that the sine of an angle is equal to the sine of its supplement. Case I (diagram 1) Case II (diagram 2) is isosceles. is supplementary to So, looks like 2 triangles can have the characteristics you describe.
