Answer:
[tex]x=27[/tex]
Step-by-step explanation:
Well based on my knowledge, all the angles of a triangle adds up to 180°. ∠D looks pretty much adjacent to ∠A. I suppose that if what I'm thinking about, ∠D and ∠A being adjacent is correct, then this is what you have to do.
∠D = 2x
∠A = ∠D
That means that ∠A is 2x.
Since all angles of a triangle adds up to 180°, you have to add up the angles of ΔABD.
[tex]72+2x+2x=180\\\\72+4x=180[/tex]
Now you subtract 72 from both sides.
[tex]4x=108[/tex]
Then you divide 4 on both sides.
[tex]x=27[/tex]
So, the value of x is 27.
Sorry if this is wrong :(
