Answer:
Infinite triangles
Step-by-step explanation:
A triangle can have angles which total to 180 degrees
When one triangle ABC is constructed with degrees 80, 80 and 40 respectively, then similar triangles can be formed by transforming ABC with a real scale factor say k
k can take any real values positive, negative, rational, irrational etc.
Hence we can say given a triangle ABC with given angles there can be an infinite number of triangles with the same angles which will be similarl to ABC and carry an equal proportion with corrresponding sides.
I believe that the right prices are

and

.
Based on that the profit per share is 11.25 - 10.5 =0.75
Now muliply the profit per share by the number of shares: 20*0.75 = 15
The profit would be 15.
