Question

if angle ADB is a right angle find the value of angle x​

Answer 1

Answer:

x+86=180

x=180-86

x=94

Answer 2

Step-by-step explanation:

Let point of interesection of two lines be O

In ∆AOE

<A + <E + <O =180°

30° + 86° + <O = 180°

<O = 180° - 116° = 64°

<COD = <AOE = 64°

In∆AOD

<A + <O + <D = 180°

64° + 90° + <C = 180° (line AD is perpendicular to CB)

<C = 180° - 154° = 26°
