Answer:
5
Step-by-step explanation:
u do 2x2 cuz of the square root and add the 1
Answer:
Given,
x=
15
2
Then,
−(−x)
=−(−
15
2
)=
15
2
As we know that by the sign rule of multiplication: (-ve) multiplied (-ve) equals (+ve)
Hence, proved −(−x)=x.
Answer:
So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880
Step-by-step explanation:
In this question we have been given the sum of interior angles of a polygon which is 2880, having n sides. We have to find n i.e the no of sides of polygon.
The formula used is S= (n-2) *180
where S= sum of interior angles
and n= no of sides
putting value of S and finding n,
2880 = (n-2) *180
2880/180 = (n-2)
16 = n-2
=> n= 16 +2
=> n= 18
So, n= 18; i.e the polygon has 18 sides and their sum of interior angles is 2880
