Answer:
<a = 90°   (180-90 supplementary angle)
<b = 90°   (180-90 supplementary angle)
<d = 48°   (180-132 supplementary angle)
<e = 132°  (opposite angle)
<c = 42°     (interior angles of a triangle equal 180.  180-48-90=42)
Step-by-step explanation:
<a = 90°   (180-90 supplementary angle)
<b = 90°   (180-90 supplementary angle)
<d = 48°   (180-132 supplementary angle)
<e = 132°  (opposite angle)
<c = 42°     (interior angles of a triangle equal 180.  180-48-90=42)
 
        
             
        
        
        
Answer:
16 km
Step-by-step explanation:
Given:
Distance from Washington to Stamford = distance from Washington to Salem + distance from Salem to Stamford = 10.3 km + 11.9 km = 22.2 km
Distance from Washington to Oakdele = 6.2 km
Required: the difference between the distance from Washington to Stamford and from Washington to Oakdele
Solution:
Distance from Washington to Stamford = 22.2 km 
Distance from Washington to Oakdele = 6.2 km
The difference = 22.2 km - 6.2 km = 16 km
Therefore, from Washington, it is 16 km farther to Stamford than to Oakdele.
 
        
             
        
        
        
Answer:
-9
Step-by-step explanation:
-2x + 3 = -x + 12
move -x over by adding
-x + 3 = 12
move the 3 over by subtracting
-x = 9
divide by - to get the x positive
x = -9
 
        
                    
             
        
        
        
W = -53 
when you add negative numbers its basically subtracting
        
             
        
        
        
Answer:
9.6 cm
Step-by-step explanation:
Since the shapes are similar, we can write a proportion. Let x be the length of MN.
 9/12 = 7.2/x	Write a proportion.
9x =	12(7.2)	Use cross products.
9x =	86.4	Multiply.
x =	9.6	Divide both sides by 9.
Side MN is 9.6 cm.
