Answer:
3y+4+2y+16=180 sum of two opposite angle of the cyclic quadrilateral is 180
5y=180-20
y=160/5=32
again
2x+58=180sum of two opposite angle of the cyclic quadrilateral is 180
2x=180-58
x=122/2=61
we know that
A quadratic equation is a polynomial with an order of two. Its general form is

case a) 

<u>The case a) is a quadratic equation</u>
case b) 
<u>The case b) is a grade
polynomial</u>
case c) 
<u>The case c) is a grade
polynomial</u>
case d) 
<u>The case d) is a grade
polynomial</u>
therefore
the answer is

A fraction equivalent to 1/5 could be 2/10
