Here is the graphed part. Hope this helped!
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°
7/8 miles = 49 / 56 miles so it will take the road crew 49 hours to repave the road.
The answer would be -3 4/3
