To find sum of the four angles, we can find the sum of 1. (angle a and angle b) and 2. (angle c and angle d). To find 1, look at triangle ABG (corresponding to angles): (angle a + angle b) = 180° - angle g. Similarly, to find 2, look at triangle CDE and angle e, to find (angle c and angle d).
I've done it for you this time but please rotate your photo properly the next time.

Here you go! They asked for the Sim of abcd so you don't have to break the angles down individually before adding them up. :)

Sum of angles in a triangle is 180°, not 360°!!
