You have to times all the numbers together to get the surface area.
So that means you have to do 16*12*5.
Answer:
A regular polygon with 48 sides
see the explanation
Step-by-step explanation:
we know that
As the number of sides of a regular polygon increase, the internal angle can come very close to 180°, and the shape of the polygon approaches that of a circle
so
As the number of sides of a regular polygon increase, the polygon gets closer and closer to a true circle
therefore
A regular polygon with 48 sides, because as the number of sides of a polygon 48, the perimeters of the polygons get closer to the circumference of the circle

We know that the triangle is made up of 180°
To find "x" we need to know the two angles of the triangle.
We also know that the supplementary angles are made of 180°
In this case the supplementary angle would the angle were 100° and the missing value is.
Since supplementary angles are made of 180°
180°-100° = 80°
Now we know the two angles of the triangle.
Since the triangle is made up of 180°
180° = x + 70° + 80°
x + 150° = 180°
x = 180° - 150°
x = 30°
