Explanation:
First, add by 25 both sides of an equation.

Then, simplify by equation and add/subtract by the numbers.

*The answer must be have a negative sign.

Hope this helps!
Thank you!
Have a great day!

Answer:
4x-y+1=0
Step-by-step explanation:
here,given equation of a line id 
4x-y-2=0.. eqn(i)
equation of any line parallel to line (i) is
4x-y+k=0...eqn(ii)
since, the line(ii) passes through (1,5)[replacing x=1 and y=5 in eqn(ii), we get]
4*1-5+k=0
or, 4-5+k=0
or,-1+k=0
•°•k=1
substituting the value of k=1 in eqn(ii),
4x-y+1=0 is the required equation of the line.
 
        
             
        
        
        
Answer:

Step-by-step explanation:
Subtract the 4 from 9
 
        
                    
             
        
        
        
Side a = 10.98991
Side b = 11.69522
Side c = 4
Angle ∠A = 70° = 1.22173 rad = 7/18π
Angle ∠B = 90° = 1.5708 rad = π/2
Angle ∠C = 20° = 0.34907 rad = π/9
