What's the rest?You only said, From 180 books to 150 books sooo you gotta put the rest or nobody will answer it.
Those two angles have to add up to 180° as that is a straight angle, so 5x - 10 + 6x + 10 = 180. combine like terms to get 11x - 10 + 10 = 180. the 10 cancels, so 11x = 180. divide both sides by 11 to get x = approximately 16.36.
FYI - I CANNOT TELL IF THAT ACTUALLY SAYS 5
I think it’s either 4 or 20
5 x 4 =20
6 x 4 =20
