Answer: 29,030,400</h3>
==============================================================
Explanation:
Let's say the mother will temporarily take the place of all the sisters. Wherever the mother sits will represent the block of girls.
Taking out the 6 sisters and replacing them with the mother leads to 7+1 = 8 people in a line.
There are 8! = 8*7*6*5*4*3*2*1 = 40,320 different ways to arrange 8 people.
----------
Again, the mother's position is where the sisters block will go. So let's say the mother was in seat #2. This would mean one brother would take seat #1, and all of the sisters would take the next six seats, until we reach seat #7 is when another brother would take the next seat.
Within any given permutation (the 40320 mentioned), there are 6! = 6*5*4*3*2*1 = 720 different ways to arrange just the girls in that girls block/group.
All together, there are 40320*720 = 29,030,400 different ways to arrange the 13 siblings where all the girls are seated together.
To find the coterminal angle to the given angle , we need to add or subtract the multiples of 360 degree . Since here we have to find the coterminal of -710 in 0 to 360, it means we have to find a positive coterminal angle . And to find the positive coterminal angle, if we add just 360 degree, we will get -710+360 = -350, but we need a positive coterminal angle, so we add again 360 , that is -350+360 =10.
So the coterminal of -710 in 0 to 360 is 10 degree .
