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:

1. Isolate the y. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
First, multiply 12 to both sides
-y/12(12) = 6(12)
-y = 6(12)
-y = 72
Isolate the y. Divide -1 from both sides
-y/-1 = 72/-1
y = -72
-72 is your answer for y

2. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
x/4 = 8
First, multiply 4 to both sides
x/4(4) = 8(4)
x = 8(4)
x = 32
32 is your answer for x

Answer:
30. $<u>25.42</u>
31. $<u>21.48 </u>
32. $<u>23.06</u>
Step-by-step explanation:
30. 8.54+7.50+9.38 = 25.42
31. 6.99+5.99+8.50 = 21.48
32. 8.50+5.33+9.23 = 23.06
