In order to get the area of a triangle using sides, the formula that we are going to use is Heron's formula. This is after from "Hero of Alexandria".
So here is the step by step process:
First, we calculate for s (half of the triangles perimeter) s = a+b+c divided by 2.
s = 6 + 10 + 12 / 2
s =28/2
s = 14
Now that we have the s, we can now calculate for the area.
A = square root of s(s-a)(s-b)(s-c)
A= square root of 14 x 8 x 4 x 2
A= square root of 896
A = 29.93
The area of triangle DEF is 29.93 square feet or 30 square feet. Hope this answer helps.
Answer:
D ) 256
Step-by-step explanation:
The given sequence is 1,4,27, ---, 3125
This is sequence of given problem
so here missing is '4' term is
The fourth term is 256.
I dont know but thanks for your points
Hi there
-5i + 5-1 + 6
= -5i + 11- 1
= 5i + 10
That's the answer :0
I hope that's help... Do you have any question ?
The correct answer is C. Aimee used the Associative and Commutative properties to put numbers that are easy to add next to each other.
