Answer:
which agrees with the first answer in the list of possible options.
Step-by-step explanation:
We can use the fact that the addition of all four internal angles of a quadrilateral must render 
. Then we can create the following equation and solve for the unknown "h":
Therefore the angles of this quadrilateral are:
