H = 26 is the given height of the equilateral triangle
s = unknown side length of the equilateral triangle
The formula to use is
s = (2/3)*sqrt(3)*h
which helps tie together the side length s and the height h
Plug in the given height h = 26 and we get...
s = (2/3)*sqrt(3)*h
s = (2/3)*sqrt(3)*26
s = 30.0222
That rounds to 30
Answer: 30
Answer:
- 10a-b+0.1c
Step-by-step explanation:
−0.1·(100a+10b−c)= - 10a-b+0.1c
Answer:
the negative exponent means that the decimal move to the left so the answer is 0.000025.
Step-by-step explanation:
2.5--->0.000025
We have given
LM=4.12
MN=4
LN=5
OM=6.4
As <span>diagonals LN and OM intersect at point R.
so we divide LN by 2
we get 5/2=2.5
now using Pythagorean theorem
OR^2= 4^2-2.5^2
</span>OR^2=9.75
taking square root
OR=3.12
so the right answer is <span>d) 3.2</span>
