Answer:
sin(π/8) = (1/2)√(2-√2)
Step-by-step explanation:
Using the half-angle formula ...

We can let θ = π/4 and simplify the result as follows:

Let x= width
Then x+3= length
So 2x+2x+6=26
4x+20
x=5
Width is x=5m and length is x+3=8m
Area is (lenght)(width) so (5)(8)= 40m squared
Answer:
After 5 hours
Step-by-step explanation:
LaRhonda charges a 10 dollar fee plus 5 hours will get her 20 dollars.
William will babysit 5 hours for 4 dollars and receive 20 dollars also.
<span>A = 2ab + 2ac + 2bc
A = 2b(a + c) + 2ac
2b(a + c) = A - 2ac
b = (A - 2ac) / [2(a + c)]</span>
Hi Kyliebreland!
So, If he saved $5 then we do $20 divided by $5 which gives 4 so now we split 100% into 4 pieces which gives us 25%.
Hope this helps!
