Answer 2

In triangle ABC

According to angle sum property of a triangle,

angle ABC + angle BAC + angle ACB = 180⁰

30⁰ + 40⁰ + Angle ACB = 180⁰

70⁰ + Angle ACB = 180⁰

Angle ACB = 180⁰ - 70⁰

Angle ACB = 110⁰

Now

Angle ACB + Angle ACD = 180⁰ [Linear Pair]

110⁰ + x = 180⁰

x = 180⁰ - 110⁰

x = 70⁰
