Answer:
Step-by-step explanation:
3 sinθ=3 cos 2θ
sin θ=cos 2θ
sinθ=1-2sin² θ
2sin²θ+sin θ-1=0
2sin²θ+2sinθ-sinθ-1=0
2sin θ(sin θ+1)-1(sin θ+1)=0
(sin θ+1)(2 sin θ-1)=0
sin θ=-1=-sin 90=sin (180+90)
θ=270
or sin θ=1/2=sin 30,sin (180-30)
θ=30,150
solution set is {30,150,270}

</span>Find the least common multiple (LCM) of the denominators in order to find the least common denominator (LCD).
which equals 3
Find the mean (arithmetic)-.<span><span>gr^2ate^2+0.5+ 23 </span>3
</span>The LCM (least common multiple) of two or more non-zero whole numbers is the smallest whole number that is divisible by each of those numbers. In other words, the LCM is the smallest number that all of the numbers divide into evenly.=<span>2grat

In other words:
0.5, 3/5, 0.65, 2/3
<span> Hope this helps
