How many triangles can be constructed with angles measuring 50,90, and 40

2 triangles

Step-by-step explanation:

The 90* angle is stable, so you can change only the position of the 50* and 40* angles.  

1 triangle: 40* is right to the 90*

2 triangle: 40* is left to the 90*

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
