Answer:

15

Step-by-step explanation:

By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is 3x-6. Simplifying the equation 3x-6=2x+1, gives x=7. Substituting x=7 in the equation for segment AC gives 15.

Please helppppppppppppppp fine x its high school geometry
Illusion [34]
First take triangle BDH. We know B is 46 degrees and D is 33 degrees. Since the angles of a triangle equal 180 we get
180 - 46 - 33 = 101 for H.
H is supplementary to x, so their sum is also 180. This gives 180 - 101 = 79.
So x is 79 degrees.
