Question

Find the value of x
6x + 12
3x - 3

Answer 1

19°

Explanation:

Concept Used :-

• The measure of a straight line is 180°. So the sum of angles on a straight line is 180° .

Using this ,

`\bf\implies 6x + 12 + 3x - 3 = 180\\\\\bf\implies 9x + 9 = 180\\\\\bf\implies 9x = 180-9 \\\\\bf\implies x =(171)/(9) \\\\\bf\implies\boxed{\red{\bf x = 19 }}`

Hence the value of x is 19°
