Answer: 0.05 cup
Step-by-step explanation:
Divide 2.5 by 10 to find how much is in one of Sarah’s dish.

Divide 1.6 by 8 to find how much is in one of Amyn's dish.
This gives you 0.2
Now minus 0.2 from 0.25.
This gives you 0.05 cup

So you know that the sum of angles in a triangle is 180°.
You know two of the angles in triangle WXZ. The two angles are angle WXZ, which is 50° and angle XWZ, which is 90°.
Now you can calculate angle WZX, by:
180-50-90=40°.
