The terminal ray of angle β , drawn in standard position, passes through the point (−5, 2√7) . What is the value of cos β ? Ente

Alexxx [7]

Step-by-step explanation:

Draw the triangle formed by the ray.

The hypotenuse of the triangle is:

c² = a² + b²

c² = (-5)² + (2√7)²

c² = 25 + 28

c = √53

Therefore:

cos β = -5 / √53

Or, as a proper fraction:

cos β = -5√53 / 53

kakasveta [241]

<h2>Hope this helps!</h2>

Answer:

$68.32

Step-by-step explanation:

Is 9.76 = x

And the value needed is 8 * this amount, then it can be shown with 8x

8x = 9.76 * 8

8x = 78.08

So the total price is $78.08

To find the money needed, simply subtract the saved money from this amount:

78.08 - 9.76 = 68.32

So she needs $68.32!
