Answer:
y=5x-11
Step-by-step explanation:
parallel lines have the same slope 5
y-4=5(x-3)
y-4=5x-15
y=5x-15+4
y=5x-11
 
        
             
        
        
        
Answer:
Step-by-step explanation:
The angle at E is 90 degrees.
All tangents of a circle always meet the radius at a 90 degree angle.
90 + 67 + G = 180o    All triangles have 180 degrees. Combine left.
157 + G = 180o           Subtract 157 from both sides.
157 - 157 + G + 180 - 157
G = 23
