Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
Sum of first 3 angles = 360° - 100° = 260°.
260° / (4 + 6 + 3) = 20°.
First angle = (20°) * 4 = 80°
Second angle = (20°) * 6 = 120°
Third angle = (20°) * 3 = 60°
The angles are 80°, 120° and 60°.
Since I can't draw, you could draw 3 pizzas and cut them all in half, so each person would get half a pizza.
A number is rational if it can be expressed as the ratio between two integers (of course the denominator can't be zero).
-1/16 is already a fraction, so it's rational.
0 can be expressed as a fraction: 
for any non-zero integer

can't be expressed via a fraction between integers, and thus they are irrational.
