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:
I would say A because it is rotated 180 degrees relative to the origin.
Answer:
The length of x is 4
Step-by-step explanation:
The scale factor is Large/small where 10/8 which is DF/AC.
THE SCALE factor is 5/4.
To find the length of X is in AB we use the scale factor 5/4 and the corresponding DE.
5/4 = DE/AB
5/4 = 5/X
X = 4
To find Y in EF will use the corresponding BC which is 6.
5/4 = EF/BC
5/4 = Y/6
Y= 7.5

Answer:
m = (5x -6)/(43y -4)
Step-by-step explanation:
Subtract 4m+6 to separate m-terms from other terms.
5x +4m -(4m +6) = 43my +6 -(4m +6)
5x -6 = 43my -4m
5x -6 = m(43y -4) . . . . factor out m
(5x -6)/(43y -4) = m . . . . divide by the coefficient of m
Answer: It is the area of the base
Step-by-step explanation:
"B" represents the area of the base so if the base is a square than a capital "B" means to find the area of the base (square). To find the area of a square it would be length x width.
