Answer:
Step-by-step explanation:
Let the coordinates of d be (x,y)
The midpoint of (x,y) and (-5,-3) is equal to ((-5+x)/2, (-3+y)/2)
this should be equal to the coordinates of e, (-6,4)
we have (-5/2+x/2, -3/2+y/2)
-5/2+x/2 = -6
-5 + x = -12
x = -7
-3/2+y/2 = 4
-3+y = 8
y = 11
Therefore the coordinates of d are (-7,11)
 
        
             
        
        
        
Lowest common multiple and I think Lowest common denominator
        
                    
             
        
        
        
Set up a proportion of 5 over 3 and then x over 17
Cross multiply to get 17x=85
Then divide by 17
To get x to equal 28.33.
x=total height.

Step-by-step explanation:
The longest side in a triangle is opposite the largest angle, and the shortest side is opposite the smallest angle. 
So the smallest angle is <P.
