Use the given information to determine the exact trigonometric value.

pashok25 [27]

Answer: $\bold{a.\quad -\dfrac{2\sqrt{6}}{5}}$

<u>Step-by-step explanation:</u>

$sin\theta=\dfrac{y}{h}\implies y=-1, h=5\\\\\\\text{Use Pythagorean Theorem to find x:}\\x^2 + y^2 = h^2\\x^2 + (-1)^2=5^2\\x^2+1=25\\x^2=24\\x=\sqrt{24}\\x=2\sqrt{6}$

$\text{Since }\theta\text{ is between }\pi\text{ and }\dfrac{3\pi}{2} \text{ (Quadrant III)},\text{ then x and y are negative.}\\\implies x=-2\sqrt{6}\\\\\\cos\theta = \dfrac{x}{h}\quad =\boxed{-\dfrac{2\sqrt{6}}{5}}$

If they share the money in ratio 7:n

And Ann had 28%

Thus unit ratio will be 28/7 = 4

Since Bill had 100 - 28 = 72%

Bill ratio will be 72/4 = 18

7:n will be 7:18

Thus the value of n is 18
