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

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

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

(6x-7)-(4+3x)=13 PLS HELP

klemol [59]

$(6x - 7) - (4 + 3x) = 13$

$6x - 7 - 4 - 3x = 13$

$(6x - 3x) + ( - 7 - 4) = 13$

$3x - 11 = 13$

$3x = 13 + 11$

$3x = 24$

$x = \frac{24}{3}$

$x = 8$
