Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
2sin(x)cos(x) - cos(x) = 0
so one solution is cos(x) = 0.
=> x = pi/2 and 3pi/2 (90° and 270°)
for cos(x) <> 0 we have then
2sin(x) - 1 = 0
2sin(x) = 1
sin(x) = 1/2
=> x = pi/6 and 5pi/6 (30° and 150°)
Do 36 divided by the amount of sides the hexagon has. I think I am not sure
Answer:
The correct answer is A) 5n = 3d and 3n + 6 = 2d + 4
hope this is right...
The answer for 6x+2=14 is x=2.
55
the four number is 26+27+28+29
so 26+29=55
