Answer:

On your calculator do 0.69x192, as that removes 0.31 of 192, or 31%.
It depends on which triangles you put together, if they are equilateral triangles, then its a diamond, if they are rectangle (right) triangles, then its a rectangle, if they are isosceles triangles, then its a really sharp diamond, and if they are scalene triangles, then the shape is like a common kite.
7/8 = 87.5%
I'm guessing it is meant to say round to the nearest 10th of a percent
If the question actually says something different comment so i can fix it
90° counterclockwise rotation
