Answer:

(d) -√((2+√2)/(2-√2))

Step-by-step explanation:

5π/8 is a 2nd-quadrant angle whose reference angle is greater than π/4. This means the tangent is negative with a magnitude greater than 1. The only reasonable choice is ...

$\displaystyle -\sqrt{\frac{2+\sqrt{2}}{2-\sqrt{2}}}$

_____

<em>Additional comment</em>

This simplifies to -(1+√2). Your calculator can verify the choice for you.

Answer:

C. 7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

distance = speed × time

300t = 350(t -1)

300t = 350t -350 . . . . eliminate parentheses

350 = 50t . . . . . . . . . . add 350-300t

7 = t . . . . . . divide by 50

The trip out took 7 hours.

an obtuse triangle has the side as x-3 on the left and then the right says x then the bottom says x+6 can you find the perimeter

user100 [1]

Answer:

P = (x-3) + (x+6) + x

P = 3x+3

Step-by-step explanation:

To find the perimeter of a figure, you just need to add all sides together. First, you need to set up an equation that adds all sides together. Then, you would need to combine like terms (x+x+x=3x); -3+6=3. So you would take 3x and add 3, since 3 is positive.

Hope this helps!
