Answer:
1.)  C = 76.1 
2.) C = 5.8
Step-by-step explanation:
 
        
             
        
        
        
Those two angles have to add up to 180° as that is a straight angle, so 5x - 10 + 6x + 10 = 180. combine like terms to get 11x - 10 + 10 = 180. the 10 cancels, so 11x = 180. divide both sides by 11 to get x = approximately 16.36. 
FYI - I CANNOT TELL IF THAT ACTUALLY SAYS 5

Answer:
The slope is 3/4 and on a graph it would be 4 over to the right and 3 down.
 
        
             
        
        
        
Acute since right triangles have a 90 degree angle and obtuse triangles have angles in between 90 and 180
