Answer:
Scalene
Explanation:
It isn’t equilateral or isosceles. Therefore it must be scalene
Answer:
I think they will match if they have a relationship so A. But, i also think it could be different it's like humans they aren't all the same. :)
Step-by-step explanation:
Those were my reasons and thats pretty much what you think or make it is what it is so best idea is to work it out. :)
We are to solve the total area of the pyramid and this can be done through area addition. We first determine the area of the base using the Heron's formula.
A = √(s)(s - a)(s - b)(s - c)
where s is the semi-perimeter
s = (a + b + c) / 2
Substituting for the base,
s = (12 + 12 + 12)/ 2 = 18
A = (√(18)(18 - 12)(18 - 12)(18 - 12) = 62.35
Then, we note that the faces are just the same, so one of these will have an area of,
s = (10 + 10 + 12) / 2 = 16
A = √(16)(16 - 12)(16 - 10)(16 - 10) = 48
Multiplying this by 3 (because there are 3 faces with these dimensions, we get 144. Finally, adding the area of the base,
total area = 144 + 62.35 = 206.35
Answer:
I'm sorry. I cannot explicitly give you an answer. The picture of the polygon is not provided. You may have forgotten to upload it, nevertheless, I''ll try my best to be of help to you.
Step-by-step explanation:
There are many different polygons. But the general formula to finding the perimeter of a polygon is:
P = n * l
n = number of sides
l= value shared and assigned to each side
The general formula to finding the area of a regular polygon is:
A = (n*l*apothem )/2
n = number of sides
l = length of one side
apothem = the value of the segment connecting the center of the polygon to a midpoint of one of the sides.
Hope this helps a little! You can always submit the question again with the picture and I'll be more than happy to help you. <3
