90 degrees counter-clockwise around the origin.
The answer is C) The quotient of some number and six
_ π/3 · sin π/6 = 1/2 · ( sin π/2 - sin π/6 )
Lets start from the right side of the equation:
1/2 · ( sin π/2 - sin π/6 ) = 1/2 · ( 1 - 1/2 ) = 1/2 · 1/2 = 1/4
So the left side must be equal:
_ π/3 · sin π/6 = 1/4
_ π/3 · 1/2 = 1/4
_ π/3 = 1/4 : 1/2 = 1/4 · 2/1 = 1/2
cos π/3 = 1/2
Answer:
cos π/3 · sin π/6 = 1/2 ( sin π/2 - sin π/6 )
Answer:
200
Step-by-step explanation:
170% of x = 680
Set up an equation:
170/100 • x/1 = 680
1.7 • x = 680
1.7x = 680
x = 400
50% of 400
1/2 • 400 = 200
49.5 - 37.5 = 12
12(2)= 24
2 times the difference between 49.5 and 37.5 is 24.
