Answer:
x = 34
Step-by-step explanation:
It is given to us that when all the interior angles are added together, it will equal 360. Set all the angles equal to 360.
3x - 6 + 2x + 88 + 108 = 360
Simplify. Combine like terms.
(3x + 2x) + (88 + 108 - 6) = 360
(5x) + (190) = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 190 from both sides.
5x + 190 (-190) = 360 (-190)
5x = 360 - 190
5x = 170
Isolate the variable x. Divide 5 from both sides.
(5x)/5 = (170)/5
x = 170/5
x = 34
34 is your answer for x.
