Answer:

about 70.0 mph

Step-by-step explanation:

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

Shalnov [3]

Answer:

19°

Step-by-step explanation:

Concept Used :-

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

Using this ,

$\bf\implies 6x + 12 + 3x - 3 = 180\\\\\bf\implies 9x + 9 = 180\\\\\bf\implies 9x = 180-9 \\\\\bf\implies x =\dfrac{171}{9} \\\\\bf\implies\boxed{\red{\bf x = 19 }}$

<h3>Hence the value of x is 19°</h3>
