Please help me find x

37°

Step-by-step explanation:

figure consists of 2 6 side polygon

sum of interior angles: 180 x (6 - 2) x 2 =1440

x = 1440 - (135 + 107 + 126 + 325 + 125 + 95 + 120 + 90 + 280) = 37°

x=37

Step-by-step explanation:

You split the figure in 2 polygons and write the equations ,knowing the sum of the angles  of a polygon is (n-2)*180 where n is the  number of the angles .

you write  the equations

125+95+120+90+a+b=4*180=720

a+b=720-430

a+b=290

and then  

135+107+126+(325-a)+(280-b)+x=720

973-(a+b)=720

973-290+x=720

683+x=720

x=720-683

x=37

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.
