Answer:
a cylinder, a sphere, and that little half sphere thing, oh and a triangular pyramid
Step-by-step explanation:
 
        
             
        
        
        
3x - 10 + x = 90
4x = 100
x = 25 degrees
        
             
        
        
        
I’m not completely sure, but I would say about 3/5 because of the fact that the X is not directly in the middle, so it can’t be 1/2 but it’s very close to the middle which could make it possible that it is 3/5?
