Answer:
Step-by-step explanation:
1. Parallelogram and rectangle
Sides: The opposite sides of both parallelogram and the rectangle are parallel and are equal.
Angles: Opposite angles of both parallelogram and rectangle are equal and adjacent angles of both parallelogram and rectangle are supplementary.
Relationship: Not all parallelograms are rectangle but all rectangles can be parallelograms.
2. Parallelogram and square:
Sides: Opposite sides of both the square and the parallelogram are parallel, but all sides are same in square but opposite sides are equal in parallelogram.
Angles: Opposite angles of both parallelogram and square are equal and adjacent angles of both parallelogram and square are supplementary.
Relationship: All squares are parallelograms but not all parallelograms are squares.
Answer:
As per the given condition: Rodrigo has a ladder that is 13 ft long. The ladder is leaned against a vertical wall. The top of the ladder is 10.8 ft above the ground.
The Orientation of the ladder with the wall forms a right triangle.
The ladder length is the hypotenuse of the triangle,
the distance between the ladder at ground level and the base of the wall is the horizontal leg of the triangle,
and the height of the ladder is the vertical leg of the triangle.
⇒ Height of the ladder = 10.8 ft and hypotenuse = 13 ft
Using sine ratio formula;

Opposite side = height of the ladder = 10.8 ft and
Hypotenuse side = 13 ft.
then;

or

Simplify:
(nearest to tenth place)
Since, it is given that the angle the ladder makes with the ground needs to be 60 degree or less for safety purposes.
(a)
Yes, this ladder in a safe position.
as 
(b)
You can see the diagram as shown below in the attachment.
Answer:
Step-by-step explanation:
9+33-6)/6-3
42-6)/6-3
36/6-3
6-3
3 to the second power is 9
because three times three is 9
