Find the value of X.

idk

step-by-step explanation:

answer is 270 degrees: -

to convert radians to degrees you multiply by 180/π

9π/ 6 * 180 / π

=   9 * 180 / 6

= 9 * 30

=   270 degrees   answer

well if you have a decimal you have to line them up and make sure the you have everything   straight and then add or subtract some thing with   division and   multiplying so just like them up

the answer would be 9 because if it is perpendicular to the green line. the red lines slope is the opposite or reciprocal of the slope of the green line.
