Answer:A polygon with 8 sides called octagon

Step-by-step explanation:

sum of interior angles in a polygon=180(n-2)

n=number of sides

1080=180(n-2)

Divide both sides by 180

1080/180=180(n-2)/180

6=n-2

Collect like terms

n=6+2

n=8

number of sides=8

Answer: $(-1.412,-2.124),(3.29,7.28)$

Step-by-step explanation:

Given

The given equation is $2^x-2.5=2x+0.7$

There are two functions i.e. $y=2^x-2.5\ \text{and}\ y=2x+0.7$

Their intersection gives the solution of the above function

From the graph, we can see that both the graph intersects at two different points i.e. at

$(-1.412,-2.124)\ \text{and}\ (3.29,7.28)$
