Answer: 118 degrees

Step-by-step explanation:

Angles on the opposite sides of rhombus will always be equal and the sum of all the angles of quadrilaterals are 360 degrees so we get the equation

2u - 70 + u + 52 + 2u - 70 + u + 52 = 360

6u - 36 = 360

6u = 396

u = 66

But, 66 is not the answer, as they want to find the angle D AKA u + 52 which is 66 + 52 = 118 degrees

Find the quotient and any excluded values.<br><br> (x + 5/x^2 + 9x + 20)/(x^2-16/x-4)
Wittaler [7]
By  <span>(x + 5/x^2 + 9x + 20) you apparently meant the following:

         x+5
 ----------------------
   x^2 + 9x + 20

and by 

</span><span>(x^2-16/x-4)
                                       x^2-16
you apparently meant ---------------
                                         x - 4

Please use additional parentheses for clarity.

Dividing,

</span>         x+5                   (x-4)(x+4)
 ----------------------  *  ---------------
   x^2 + 9x + 20                  x-4

Now, x^2 + 9x + 20 factors into   (x+4)(x+5), so what we have now is

       (x+5)(x+4)
------------------------- = 1           This is true for all x, so there are no exclusions.
    (x+4)(x+5)

Check picture below, solve for "x" and "y"

unless you've already covered the 30-60-90 triangle, then check your book on them, to see the ratios, using the 30-60-90 ratios is simpler
