Mathematics

The measure of the angle with vertex and the endpoints of the sides lying on the circle is half the measure of the intercepted arc. If the quadrilateral is inscribed in a circle, the sum of the measures of the intercepted arc is 360 degrees representing the whole circle.

This means that the sum of the opposite angles is 180 degrees.

Mandarinka [93]

Answer:

The word "ARRANGE" can be arranged in

2!×2!

7!

=

4

5040

=1260 ways.

For the two R's do occur together, let us make a group of R's taking from "ARRANGE" and permute them.

Then the number of ways =

2!

6!

=360.

The number ways to arrange "ARRANGE", where two "R's" will not occur together is =1260−360=900.

Also in the same way, the number of ways where two "A's" are together is 360.

The number of ways where two "A's" and two "R's" are together is 5!=120.

The number of ways where neither two "A's" nor two "R's" are together is =1260−(360+360)+120=660.
