Answer:

To find the area of a regular polygon, all you have to do is follow this simple formula: area = 1/2 x perimeter x apothem. Here is what it means: Perimeter = the sum of the lengths of all the sides.

The brilliant plumage of what national bird of india is due to an optical interference phenomenon called the bragg reflection?

attashe74 [19]

The correct answer is the peacock. The plumage found in Indian peacocks are because of the Bragg reflection phenomenon.

Explanation:

Bragg's law, or Wulff–Bragg's position, a special event of Laue diffraction, gives the plans for coherent and incoherent scattering from a crystal lattice. When X-rays are conflicted on an atom, they make the electronic cloud move as does an electromagnetic wave and it is observed in peacock.

What type of angle is it? What is the measurement?

romanna [79]

Below I have included an image that has the measure of all of the angles on it.

We can find the measures of the angles here due to the laws about complimentary angles. A pair of complimentary angles can be formed when 2 lines are perpendicular, and when added together, will always equal 90. The pair are the angles that are not directly adjacent from each other. In this figure, "x" and "(4x-10)" are a pair. According to another law, opposite angles, or adjacent angles, will always be equal to each other. Using the logic above is how we can find the measure of all angles.

Since one angle has a box, we know the lines are perpendicular, and that the laws of complimentary angles apply. We can also use that to see that the angle diagonal from it is equal to 90.

To solve for the other measures, we need to add the 2 equations together and set them equal to 90 (because of that law we talked about before).

x+(4x-10)=90
5x-10=90
+10+10
5x=100
/5 /5
x=20

Now that we know x equals 20, we can substitute that value in and solve.

x=20

=(4x-10)
=(4*20-10)
=(80-10)
=70

We also know this is correct because 20 and 70 equal 90.
