Plz help been stuck on this for awhile

Kazeer [188]

Answer:

d = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

d = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$

d = $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

d = $\sqrt{(-7)^{2} + (5)^{2} }$

d = $\sqrt{49 + 25}$

d =  $\sqrt{74}$ or 8.60

If cos ⁡x=−4/5, and 180°

Vladimir [108]

Answer:

180< x < 270 so x is in 3rd quadrant ,hence tan x is positive cos x=-4/5 tan(x/2) = √ {(1 − cos x) / (1 + cos x)) = √ { (1+4/5)/(1–4/5) } =√{ 9/5)/(1/5) } =√9=±3 now ...
