Answer:
AB is A
BC is B
AC is D
Step-by-step explanation:
To find the length of each side, use the formula for the distance between coordinate pairs.
We can find the distance using the distance formula:
<u>AB</u>
We then substitute (-3,6) as 
and (2,1) as 
.
<u>BC</u>
We then substitute (2,1) as and (9,5) as .
<u>AC</u>
We then substitute (-3,6) as and (9,5) as .
Answer: just multiply 9 and y together: 9 x y
Answer:
36√3 + 144
Step-by-step explanation:
Given that,
base of the pyramid is an equilateral triangle with sides = 12
Formula to calculate total surface area of pyramid
<h3>
[Base Area] + 1/2 × Perimeter × [Slant Length]</h3>
Base Area
1/2 (height) (base)
1/2 (√12²-6²)(12)
6(6√3)
36√3
perimeter of base
sum of all sides = 12 + 12+ 12
= 36
slant height = √10²-6²
= 8
put all these values in the formula above
36√3 + 1/2(36)(8)
36√3 + 144
Total area for the pyramid with the equilateral base =
36√3 + 144
Answer:
92 minutes
Step-by-step explanation:
Find the average of the numbers by adding them all together, then dividing the sum by three.
