Answer:
Consider this< as angle
<ACD= 130
So <ACD+ < ACB =180 ( linear pair)
130 + < ACB = 180
BY USING TRANSPOSITION METHOD
< ACB = 180 -- 130
= 50
As angle AC = BC
Then angle 50 = < B
SO < B = 50
NOW. :- <A + <B + <C = 180 ( BY USING ANGLE SUM PROPERTY.)
X + 50 + 50 =180
X + 100= 180
X = 180 - 100
X = 80
