Answer 2

hey !!

here the ans are...___

Square and square roots
1=1                    6=36                 11=121
2=4                     7=49                  12=144
3=9                     8=64                 13=169
4=16                   9=81                  14=196
5=25                   10=100               15=225


Cube and cube roots 
1= 1                    6=  216                              11=1331
2=  8                   7= 343                               12=1728
3=  27                  8=  512                             13=2197
4=   64                 9=  729                             14=2744
5=  125                 10= 1000                          15=3375


The different types of angles and their properties are...
Acute angle : an angle less than 90°
Right angle : an angle which is exactly 90°
Obtuse angle: an angle that is greater than 90°and less than 180°
Straight angle: an angle that is exactly 180°
Reflex angle: an angle that is that is greater than 180°and less than 360°
Full angle : an angle that is exactly 360°


hope my ans helps u dear..
