Answer:
ΔABC is a isosceles triangle at A
=> ∠BAC = 180 - 2.∠ABC = 180 - 2.65 = 50°
because AB//CD => x = ∠BAC = 50°
Step-by-step explanation:
base angles of isosceles triangle is always equal.
the sum of 3 angles of a triangle is 180'
the alternate angles in a parallel line are equal to each other.
