Answer:
x = 78 degrees
Step-by-step explanation:
All triangles add up to 180 degrees. If you can see, the star has a triangle in the middle, Triangle BJE. Angle D is given as 31 degrees, and this means that Angle E is also 31 degrees, since they are the same. In the Triangle BJE, we now have 2 angles, 47 and 31.
So add these 2 together:
47 + 31 = 78
180 - 78 = 102
This means that Angle BHI is 102, and since a straight line is 180, to find x, all you need to do is subtract 180 - 102:
x = 78 degrees.
