Angle AEB and angle CED are vertical angles, this means they equal each other, therefore we set their values as an equation and solve:
5x-10=3x+40
Subtract 3x to both sides
2x-10=40
Add 10 to both sides
2x=50
Divide both sides by 2
x=25
After we have gotten the value of x we can plug it in into the equation of angle AEB:
5x-10
Substitute x by 25
5(25)-10
Distribute
125-10
Substract 
115
The measurement of angle AEB is 115
Hope it helped!, have a great day.

Pulling out like terms
 4.1     Pull out like factors :
   -12n - 48  =   -12 • (n + 4) 
Equation at the end of step

:
  -12 • (n + 4)  = 0

Equations which are never true:
 5.1      Solve :    -12   =  0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
 5.2      Solve  :    n+4 = 0 
 Subtract  4  from both sides of the equation : 
                      n = -4
One solution was found :
 n = -4
 
        
                    
             
        
        
        
(8) = x +1
same thing as 8 = 1x
divide both sides by 1 and x = 8 Y= 8
        
             
        
        
        
Answer:2.18 m
Step-by-step explanation:
When you draw it it forms a right angled triangle. In order to get the height we must use sine.
The sine of 27° is the height divided by 4.8 m
