Answer: 10
I think it's D + .2 = ? i'm not sure but it might be something like that
Suplementary is angles add up to 180 degrees
C=180-D
C=180-84
C=96 degrees
Hope this helped :)
Answer:
let remaining angle in heptagon be a.
a+64=180(linear pair)
a=116
again
x+155+90+163+a+121°=720(sum of interior angle of hexagon is (6-2)×180°)
x+529+a=720
x+116=720-529
x=191-116=75
12 is the greatest number because it is the highest common factor between the three numbers.
