Answer:
if thisa is a triangle then 180-30+30 = 120 degree and we say all angles on a triangle add up to 180
Then reaply the rule changing 180 to 360 on all 4 sided shapes 
180(n-2) to all other shapes.
ie) pentagon 180(n-2) = 540 
continue with 540-30-30 = 480 etc....
Step-by-step explanation:
 
        
             
        
        
        
Divide 5.6 by 8 which is 0.7. Since the image of the ant is 8 times bigger we need to divide by 8 to make it actual size. 
The ant's actual length is 0.7 cm. 
        
             
        
        
        
Well lets start by getting y. We already know that all angles of a triangle will equal 180 degrees. 
Therefore we know that 65 + 65 + y = 180. To solve for y we just add the two 65's then subtract that from 180
y = 180-130 = 50 Therefore y = 50
Now lets solve for x. We know that since angle B is flat it is equal to 180. The unknown value of angle B = 180 - 65
Therefore that unknown value = 115
As we previously stated all angles of a triangle equal 180. We can now come up with this equation: 115 + x + x = 180
2x = 65
x = 32.5
