The value of x is_degrees.

x = 21

Step-by-step explanation:

The angle marked (6x - 21) and the angle marked 75 are supplementary angles. This means that they add up to 180 (by definition). We know this because they lie on a straight line, and a straight line is always 180 degrees. Then we can set up an equation:

(6x - 21) + 75 = 180

6x + 54 = 180

6x = 180 - 54 = 126

x = 126/6 = 21

Thus, x = 21.

Hope this helps!

you should at least use a calculater

step-by-step explanation:

x = 17

step-by-step explanation:

1st step: isolate x.

24 - 3x = -27

-24         -24

-3x   =   -51

2nd step: divide.

-3x     =   -51

  3             3

  x       =     17

hope this
