Find the value of x.
with work plz

x = 117 degrees.

Step-by-step explanation:  The sum of the interior angles of a pentagon should equal 540 degrees. The value of x has to make the total of the angles equal to 540.  140 + 138 + 59 +86 is 423.  Now we need to subtract 423 from 540 to know the value of x since it has to all add up to 540. 540-423 is 117.

117°

Step-by-step explanation:

sum of angles of a polygon=(n-2)*180

where n is the number of sides.

it has 5 sides.

x+86+140+138+59=(5-2)*180

x+423=3*180

x=540-423

x=117°

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
