Answer:
31
Step-by-step explanation:
There are 2 isoceles triangles in this picture, which the first one has a 56 angle, so the bottom angle is each equal to: (180 - 56) : 2 = 62
The bottom right angle + the top angle of the second isoceles triangle = 180 => the top angle = 118
It is also isoceles, so the bottom angle (or x) is equal to : (180-118) : 2 = 31
Hope it helps :)
