Answer:
x = 7
Step-by-step explanation:
=> 9/72 = 3x-20/56 
=> 9×45/72 = 3x-20
=> 27/3 = x 
=> x = 7 
 
        
             
        
        
        
Answer:
Value of x --> 15°
<u>Step-by-step explanation:</u>
(2x + 60°) and 6x lie on a straight line. So, they form a linear pair. Their sum gives 180°.
---> (2x + 60°) + 6x = 180° 
      2x + 60° + 6x = 180° 
      8x + 60° = 180°
      8x = 180°- 60°
      8x = 120
       x = 
<h3><u>x equals 15°</u></h3>
 
        
             
        
        
        
Check the picture below.
with negative angles, we go "clockwise", the same direction a clock hands move.
so -360-360-125 = -845.
so as you see in the picture, you go around twice, and then a little bit more, an extra 125°, landing you at -125°, or its positive counterpart, 235°.
