Answer:
I believe that x = 15
Explanation:
The purple triangle has only one degree showing which is 40
A triangles degrees being added together equals 180
For the purple triangle the degrees it has is 40, 40, and 100
180 - 100 = 80
There are now two degrees for the blue triangle, 85 and 80
85 + 80 = 165
180 - 165 = 15
