Answer:
8
Step-by-step explanation:
Considering the given value of sum of interior angles with exclusion of one to be 1070 then we can write it as
1070=180(n-2) where n is the number of sides required here.
Making n the subject of the formula then following step by step
![n-2=\frac {1070}{180}](https://tex.z-dn.net/?f=n-2%3D%5Cfrac%20%7B1070%7D%7B180%7D)
![n=\frac {1070}{180}+2\\n=7.9444444444444\approx 8](https://tex.z-dn.net/?f=n%3D%5Cfrac%20%7B1070%7D%7B180%7D%2B2%5C%5Cn%3D7.9444444444444%5Capprox%208)
Therefore, the shape is octagon and it has 8 sides.
Answer:
It is a quadrilateral.
Step-by-step explanation:
Quadrilateral is a 4-sided shape where the total angles is 360°.
So when you add up all the angles, you will get 360°.
Answer:
(- 3, - 4 )
Step-by-step explanation:
Under a reflection in the line y = - x
a point (x, y ) → (- y, - x ) , thus
(4, 3 ) → (- 3, - 4 )

Answer: 4/5 or 80%
Step-by-step explanation:
10 total
2 are white (2/10)
8/10 of the marbles are not white
8/10 can be reduced to 4/5
as a percent, it is 80%
