Answer:
8.7 is your answer
Step-by-step explanation:
3 metres from one end to the third mark
Solution:
Total length of wood = 10 metre
Wood is marked into 10 equal length.


= 1 metre
Length of each marking = 1 metre
Number of metres from one end to third mark = 1 + 1 + 1 = 3 metre
The image of the marking is attached below.
Hence 3 metres from one end to the third mark.
To "rationalize the denominator" is another way to say, getting rid of that pesky radical at the bottom.
we'll simply start by multiplying top and bottom by the "conjugate" of the denominator, recall difference of squares, anyhow, let's do so
39 homes
because if you put in 60 for 20 you would have to multiply 3 to get 60 so you do 3x13 and it would equal 39
Firstly triangle OAB is equilateral so R = AB =OA = 8 in
MES (ARC AB) = R x Ф (in Radian). Note that 60° =π/3
MES (ARC AB) = 8 x π/3 (D)
