In the figure shown, what is the value of x?
(1) AD = BD = CD
A.png [ 47.69 KiB | Viewed 976 times ]
from the figure we can see that the lines composing the triangle can move, but x is anchored.
Sufficient.
(2) y = 140
B.png [ 48.58 KiB | Viewed 979 times ]
the base of the triangle is fixed, but the top can move, in doing so the measurments of x will change
Insufficient.

(1) AD = BD = CD
Refer attached image
In triangle ABC,
Angle A+ Angle B+ Angle C= 180
X+20°+60°+X+40° = 180
2X+120 = 180
2X = 60
X = 30
(Sufficient)
(2) y = 140
We have no information about the relation between ABD and ACD to draw out the X value.
(Insufficient)
Answer is A
