The relationship between the top 20 students is also slight, so the top 20 students are more university-like than all secondary students.
know what is the third side length
the difference between the 2 other sides < the greatest side of triangle < the sum of 2 other sides
so here the answers here could be ( 10- 17 - 20)
10-8 < 13 < 10+8
13-8 < 17 < 13+8
13-8 < 20 < 13+8
12 adult elephants, 6 young elephants = 18 total :)
the sum of interior angle of the given polygon be give by the following formula:-
n-1×90 (where n is the no. of side of polygon)
there are 10 side in the given polygon.
on putting the value of n in the formula, we get :-
sum of interior angle is =10-1×90
sum of interior angle is =9×90
sum of interior angle is = 810 degree.
