I NEED HELP ASAP LOL ITS FOR A TIMED TEST SO YEAH HAHAHHA JUST FIND THE VALUE OF X I DONT THINK ITS THAT HARD BUT I NEED CLARIFICATION THANK YOU <3

6) 121 degrees

7) x=7

8) x=13

Step-by-step explanation:

6) Extending lines to make a trapezoid & using supplemental angles to get corner angles of 3 corners of the trapezoid.

Each corner angle =180-the two supplemental angles.

360-82-64-133=81 degrees

180-81-40=59

180-59=121

7) The central angle of an octagon (for each segment) is 45 degrees.

180-45=135 degrees which is equal to 16x+23

16x+23=135

16x=112

x=7

8) Not sure exactly how to explain this but here goes:

m1=180-(3x-6)-41=133-3x

m2=180-(7x-11)-62=129-7x

m3=180-(4x+7)-(6x-5)=178-10x

m1+m2+m3=180

133-3x+129-7x+178-10x=180

-20x+440=180

-20x=-260

x=13
