WALT Reasoning in geometry

 

Today we were learning about Geometry we had 6 questions. and here is one of them, I will be explaining how I solve it, first you gotta find out what kind of angle this is, this is called a Straight angle, which is 180 degree then next I found out that it was divided by 3 so I did.

180 divided by 3 = 60 so the X = 60
