All four angles are exterior angles of the quadrilateral.

We know that the sum of exterior angles of any polygon is 360 ° .

So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °

To solve this you would make a triangle, Assuming you had a piece of paper.

It would look like the picture included (where ever that is) sorry for the horrible drawing with mouse.

You can then you Pythagorean Theorem to solve this

$a^{2} + b^2 =c^2$

width will be (a)

put in your variables

$a^2 + 72^2 = 90^2$
$a^2 + 5184 = 8100$

Subtract 5184 over and get
$a^2 = 2916$

square root both sides and get
a=54

the field is 54 meters wide
