Solution:

A Polygon is said to be regular if it's all sides and all angles are equal.

And We define polygon as a simple closed curve entirely made up of line segments.

There are five types of Quadrilateral.

A.Quadrilateral regular→→Regular(Square)

1. Parallelogram 2. Rhombus 3. Square 4. Rectangle 5. Kite

Square is a regular polygon which is a quadrilateral.

2. Pentagon Regular is called Regular pentagon.→→Regular

3. Pentagon irregular means, not all sides as well as all angles equal.

4. Quadrilateral irregular  are Parallelogram , Rhombus and kite.

Since they are similar both dimensions would have the same ratio. The ratio of 5 and 15 is 3. 15 is 3 times larger than 5, so the unknown dimension is 3 times larger than the known dimension.

3 x 10 = 30

The unknown dimension is 30

Graph (1,1), (1,2), (1,3), (1,4)
jenyasd209 [6]

Answer:

There is not a way that I can show you how to graph it, so I will try and explain it.

Step-by-step explanation:

(1,1)

^  ^     y-axis

x-axis

You are just going right however many, and then up however many it says.

So if it's (1,1) you will go right one space, and then up one space.

Once you have all of your points on the graph, you put a line through them.

Hope this helps! :)

Find the approximate value of each trigonometric function.
vodka [1.7K]

Answer:

<u>Given</u>

  • tanθ = 3.454
  • θ is in the III quadrant

We know in the III quadrant both sine and cosine are negative.

<u>Use the following identities to get values of sinθ and cos θ</u>

  • sinθ = - tanθ/√(1 +tan²θ)
  • cosθ = - 1/√(1 +tan²θ)

<u>Substitute the value of tanθ and find sine and cosine:</u>

  • sinθ = - 3.454/√(1 + 3.454²) = - 0.961
  • cosθ = - 1/√(1 + 3.454²) = - 0.278
