Angle θ lies in the second quadrant, and sin θ = 3/5.<br> cos θ = <br><br> tan θ =
storchak [24]

Answer:


cos\Theta =\frac{4}{5}



tan\Theta =\frac{3}{4}


Step-by-step explanation:

Given : sin θ = 3/5

To Find : value of cos θ and tan θ

Solution :

use the identity:


sin^{2}\Theta +cos^{2}\Theta =1


putting value of sin θ


⇒ (\frac{3}{5})^{2} + cos^{2}\Theta =1


⇒\frac{9}{25} +cos^{2}\Theta =1


⇒cos^{2}\Theta = 1-\frac{9}{25}


⇒cos^{2}\Theta = \frac{16}{25}


⇒cos\Theta = \sqrt{\frac{16}{25}}


⇒cos\Theta =\frac{4}{5}


Thus , cos\Theta =\frac{4}{5}

Now to find value of tan θ


Since we know that


⇒ tan\Theta =\frac{sin\Theta }{cos\Theta }   (identity)


⇒tan\Theta =\frac{\frac{3}{5} }{\frac{4}{5} }


⇒tan\Theta =\frac{3}{5}\div \frac{4}{5}


⇒tan\Theta =\frac{3}{5}\times  \frac{5}{4}


⇒tan\Theta =\frac{3}{4}


Thus , the value of


tan\Theta =\frac{3}{4}


cos\Theta =\frac{4}{5}

PLZ HELP HIVE BRAINLYWho got the better deal in the Columbian Exchange: the Europeans or the Native Americans? Why?
Vitek1552 [10]

Answer:

the Europeans got the better deal from the Colombian Exchange

Step-by-step explanation:

In general, one would have to say that the Europeans got the better deal from the Columbian Exchange in that it facilitated the eventual establishment of colonies in the New World. That's not to say that it was all one-way traffic; however, the people of the New World undoubtedly benefitted in both the short and long-term by the introduction of crops and livestock. But such benefits proved to be more keenly felt by subsequent waves of European settlers than America's indigenous population.

After all, it wasn't much good for Native-Americans to have all these crops and all this livestock if, in due course, there'd be less land available for their use due to increased colonization. The indigenous peoples also suffered terribly from the introduction of diseases such as measles and smallpox, for which they had no natural immunity. It's difficult, then, to avoid the conclusion that the Europeans got the better deal from the Columbian Exchange (as it was probably intended that they should).

simply -

The Natives did benefit, but only for a short while, and the Europeans benefited the most
