Answer:
The measurement of the required angle = 116°
Step-by-step explanation:
Let the measure of its supplement = x
The measurement of the required angle = 2x - 12
 x + 2x -12 = 180
3x - 12 = 180
3x = 180 + 12
3x = 192
x = 192/3
x = 64°
The measurement of the required angle = 2 * 64 - 12 = 128 - 12 = 116°

Answer:
the numbers are 31 and 14
Step-by-step explanation:
since the larger number is 17 more than the smaller number,
larger number= x
smaller number= x-17
x-17+x=45
2x=45+17
2x=62
x=31
x-17=31-17
 
        
             
        
        
        
Answer:
