Hi I really need this question answered use the screenshot

The picture is at the bottom

Step-by-step explanation:

Here are all of the angles:

use these rules:

-the diagonals bisect the angles they cut into

- the diagonals form a 90 degree angle with each other

- the interior angles of a triangle add up to 180 degrees

- the opposite angles of a smaller where the smaller diagonals are, are equal

- the total angles of a quadrilateral is 360 degrees

so, converting firstly the mixed fractions to improper fractions and then "adding".
