Answer:
Part 10)
a) 
b) 
c) 
d) 
Part 12) x=11
Part 14) see the explanation
Step-by-step explanation:
Part 10) we know that
In a square all four sides are congruent
The diagonals of a square are congruent and bisect each other at right angles
Part a)
Find the length of diagonal OM
we know that
---> the diagonals are congruent
we have

therefore

Part b)
Find the length of PN
we know that
---> remember that the diagonals bisect each other

we have

substitute

Part c)
Find the length of ON
Applying the Pythagorean Theorem

we know that
----> remember that all four sides are congruent
so


substitute




simplify

Part d)
Find the length of MN
we know that
----> remember that all four sides are congruent
we have

therefore

Part 12) we know that
The diagonals of a square bisect its angles
Remember that the interior angles of a square is 90 degrees
so

solve for x

Part 14) we know that
A parallelogram has opposite parallel sides, so a parallelogram will always have consecutive supplementary angles.
The rectangle, rhombus and a square are all parallelograms
therefore
parallelograms, rectangles,rhombi and squares will always have consecutive supplementary angles.
Answer:
a screw is a simple machine that works as a modified inclined plane. You can think of the thread of the screw as an inclined plane wrapped around the shaft of the screw. The slope of the screw is the distance for one complete rotation while the height of the inclined plane is the distance between the threads, known as pitch. The relationship between the pitch and circumference of the screw gives the mechanical advantage.
