Using Law of Sines for the ambiguous case: SSA :

Given the triangle with the following sides: A = 25 degrees, a = 8 cm, and b = 15cm , we begin by drawing a "vague triangular diagram":

Step 1: Find the value of h ( this determines how many triangles you will have) :

Step 2: Draw in the side, a, to make an acute angle at B and darken in this triangle.

Step 3: Using Law of Sines, find the missing sides and angles of this triangle :

B1 =

C1 =

c1 =

Step 4: Now you will draw a second triangle below, making an obtuse angle at B. Now find the values of the missing side and angles of this triangle:

B2 =

C2 =

c2 =
