Answer:
Step-by-step explanation:
E = {1, 3, 7, 9, 11, 13, 15}
P= {3, 9, 11, 13} and Q = {3,7,9,15}
P' = {1, 7, 15} and Q = {1, 11, 13}
Answer: 12a-a (hope this helps :)
=12a-1a
=12a+-1a
=a+a+a+a+a+a+a+a+
=a+a+a+a+a+a+a+a+
=11A
Answer:
I'm not sure how far it has to go but from what i know this is what I came up with

x=4
Answer:
General solution
<em> θ =</em><em></em>
<em>Put n=1 </em>
<em> θ</em> = 210°
put n =2
<em> θ</em> = 330°
put n=3
<em> θ</em> = 270°
Step-by-step explanation:
<u><em>Explanation:-</em></u>
<em>Given equation </em>
<em> sin 2θ cosθ + cos 2θ sinθ = -1 </em>
<em> we know that </em>
<em>Sin (A+B) = sin A cos B +Cos A sin B </em>
<em> sin( 2θ+θ) = sin (180+90)</em>
<em> = </em><em></em>
<em> sin 3θ = sin (3π/2)</em>
<em>General solution of sinθ = sinα </em>
<em> θ = 2 n π ±α</em>
<em> 3θ = 2 n π ±3π/2</em>
<em> θ =</em><em></em>
<em> θ =</em><em></em>
<em>Put n=1 </em>
<em> θ=</em> = 210°
put n =2
<em> θ=</em> = 330°
Put n=3
<em> θ=</em> = 270°
