Answer:
Right angle 90 degrees is always going to be a right angle.
Step-by-step explanation:
 
        
             
        
        
        
2x+3=17 
subtract 3 from each side
2x+3 -3 = 17 -3
2x = 14
divide by 2 on each side
2x/2 = 14/2
x = 7
 
        
                    
             
        
        
        
Transformation involves changing the position of a shape.
The transformation from  to
 to  is 90 degrees clockwise rotation
 is 90 degrees clockwise rotation
Using the coordinates of A and A', we have:


Notice that the x-coordinate is <em>negated </em>and then <em>swapped </em>with the y-coordinate.
i.e.

The transformation of a point from <em>(x,y) to (y,-x)</em> is a 90 degrees clockwise rotation.
Hence, the transformation from  to
 to  is 90 degrees clockwise rotation
 is 90 degrees clockwise rotation

Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120  km
b=70  km
β=28 degrees (
∘)
  
b^2=(a^2)+(c^2)−2ac*cosβ  
70^2
=(120^2
)+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )  
  (c^2
) −211.907c+9500=0  
  
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500  
D=(q^2
