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°
In this scatter plot; we have people ages 10-80 years of age & the amount of texts sent per day. As one can tell by reviewing the graph; the highest amount of texts were sent at roughly the ages of 18-20. With this, the lowest amount of texts sent per day were between the ages of 70-80. We see a skyrocket between ages 10-20 in amount of texting however then we see a decent in average amount of texts as one ages.
The height of the portion AB is 10 divided by cos 50 degrees if the CAB, is bent at point A after a storm. The tip of the lamppost touched the ground at point C.
<h3>What is trigonometry?</h3>
Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
From the right-angle triangle:
Let's suppose the height of the portion AB is x ft
We know cos is the ratio of the adjacent to the hypotenuse.
From the figure:
ft
Thus, the height of the portion AB is 10 divided by cos 50 degrees if the CAB, is bent at point A after a storm. The tip of the lamppost touched the ground at point C.
