ABCDEFGH is a regular octagon. The minimum degree of rotation by which this octagon can map onto itself is (30 ; 45 ; 90 ; 120 °

). It will take ( 2 ; 4 ; 6 ; 8 ) increments of that degree of clockwise rotation for A′ (the image of A) to coincide with C.

Answer:

45°

2 - Clockwise

Step-by-step explanation:

ABCDEFGH is a regular octagon.

The minimum degree of rotation by which this octagon can map onto itself.

For rotation we have to find the central angle of each side.

Complete angle = 360°

A regular octagon has 8 equal sides. All sides make same angle at center.

8Ф = 360°

Ф = 45°

If we rotate regular octagon by 45° then it map onto itself.

Hence, 45° correct answer.  

After 2 times clockwise rotation by 45° each time. We will get the image of A coincide with C as shown in attach figure.

C is second vertex of A.

Since the center is 360 degrees, divide by 8 to find the measure of each angle formed by drawing a radius to each vertex. This gives you 45 degrees. To move A to C would take two rotations which is (45)*2= 90 degrees

What are the rules to solving equations by multiplying or dividing?
Andreas93 [3]

Answer:

In order to move a number that is multiplied or divided by the variable, make sure to inverse both sides! That means, if the number is multiplied, you divide it by both sides. If it's divided, you must multiply it by both side; steps so that you can apply them to harder equations.

Sorry if this didn't help! I hope it did though, good luck. <3

Every integer number is also a. Irrational number b. Whole number c. Natural number d. Rational number
const2013 [10]

Answer:

Option d

Step-by-step explanation:

Other options are not eligible because

a) Integers are not irrational

b)Whole numbers start from 0 and consists positive integers only.But integers consist negative integers also.

c)Natural number consists of positive integers only.

If the question had been asked as some integers are also, then options b) and c) could have been written . But in this case , it is asked every integer is also.

Thank you!
