theta is in the fourth quadrant where the cosine is positive.

the third side in the triangle = sqrt (4 - 2) = sqrt2

So sin theta = -sqrt2/2 = Second choice (negative because sine is negative in 4th quadrant)

tan theta = - sqrt2 / sqrt2 = -1

The inequality for this situation is given by 50 + p > 85

<h3>What is an inequality?</h3>

An inequality is an expression that shows the relationship between two or more numbers and variables.

Let p represent number of pages from Monday to Friday.

Jerome wants to have read at least 85 pages by the end of the day on Friday, hence:

50 + p > 85

The inequality for this situation is given by 50 + p > 85

Answer:

$x1 = 2 \\ x2 = - \frac{3}{2}$

Step-by-step explanation:

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a} \\ x = \frac{1 + - \sqrt{ {( - 1)}^{2} - 4(2)( - 6) } }{2(2)} \\ x = \frac{1 + - \sqrt{1 + 48} }{4} \\ x = \frac{1 + - \sqrt{49} }{4} \\ x = \frac{1 + - 7}{4} \\ \\ x1 = \frac{1 + 7}{4} = \frac{8}{4} = 2 \\ x2 = \frac{1 - 7}{4} = - \frac{6 }{4} = - \frac{3}{2}$
