From the attachment:

Because it is a rhombus (all equal sides), then the following relationship exists between the angles

Considering triangle RSU.

This gives:




<em></em>
<em> --- Opposite angle of a rhombus</em>
NO!!!!!!! 1450/7 is correct because 6x+x=1456 7x=1456 x=208
from the given equation
X+Y=20-->i
X-Y=14--->ii
add eq i and eq ii
2x=34
x=17
putting the value of x=17 in eq i
17+y=20
then y = 3 so the right answer is
17 and 3
I think this is the answer to that,,, >y = 5x^2
