Answer 2

Answer:

$\pink{ \boxed{x = 70}}$

Step-by-step explanation:

In ∆ABC,

$\bf \angle \: A = X$

$\bf \angle \: B = 50°$

$\bf \angle \: ACB = y \\ \bf\angle \: ACD = 120°$

We know that,

Exterior angle is sum of interior opposite angles

$\bf \angle \: ACD = \angle \: A + \angle \: B$

120° = x + 50°

120° - 50° = x

x = 70

hope this is your answer ✌️☺️
