Answer: x=5√3(you've got it correct!)
y=15
In∆ADC,
Cos 60°=DC/10
DC=5
y=20-5
y=15
Answer:
Rows are the steps - they go left to right and are numbered 1,2,3,... Columns are the columns - they go up and down and are lettered A,B,C,... Cells are defined by the row and column they are in.
Step-by-step explanation:
Answer: Any Rhombus is a Parallelogram with all its sides equal in lenght.
Step-by-step explanation:
In order to answer the given question it is important to know the following:
1. By definition a Quadrilateral is a flat shape that has four sides and four vertices.
2. A Parallelogram is defined as a Quadrilateral whose opposite sides are parallel and equal in length, therefore, its opposites angles are congruent (or have equal measure).
3. A Rhombus is defined as a Quadrialteral whose opposite sides are parallel and its opposite angles have also equal measure (They are congruent). All the sides of any Rhombus have equal lenght.
Therefore, based on the explained before, you can conclude that any Rhombus is a Parallelogram with sides that have all equal lenght.
The answer is 1/10
If you do 1/2 divided by 5 you will get 0.1 or 1/10
