Answer:
x = 9° (or) 8x = 72° 
Explanation:
Now we have to,
→ find the required value of x. 
We know that,
→ Straight line is always 180°. 
Forming the equation,
→ 8x + 108° = 180° 
Then the value of x will be,
→ 8x + 108° = 180° 
→ 8x = 180° - 108° 
→ 8x = 72° 
→ x = 72° ÷ 8 
→ [ x = 9° ] 
Hence, the value of x is 9°.
