Answer:

Linear pair of angles:

If Non-common arms of two adjacent angles form a line, then these angles are called linear pair of angles.

Axiom- 1

If a ray stands on a line, then the sum of two adjacent angles so formed is 180°i.e, the sum of the linear pair is 180°.

 

Given :  ∠ACB is a line such that ∠DCA = 5x and ∠DCB = 4x.

∠ACD and  ∠DCB form a linear pair.

∠ACD + ∠DCB = 180°  

5x + 4x = 180°

9x = 180°

x = 180°/9

x = 20°

Hence, the value of x is 20°.
