Answer:
AC = 15
Step-by-step explanation:
3x + 4x + 8 = 5x + 10
7x + 8 = 5x + 10
2x + 8 = 10
2x = 2
x = 1
5(1) + 10 = 15
 
        
                    
             
        
        
        
Answer:
x = 12
Step-by-step explanation:
Remark
These two angles are corresponding angles and as such, they are equal.
Equation
8x+ 36 = 5x + 72 
Solution
Subtract 5x from both sides
8x - 5x + 36 = 5x - 5x + 72          Combine like terms.
3x + 36 = 72                                 Subtract 36 from both sides
3x + 36 - 36 = 72 - 36                  Collect like terms
3x = 36                                          Divide by 3
3x/3 = 36/3                                   Divide
x = 12                                             Answer
