Answer:

  • [tex]\sf x=20^o[/tex]

Step-by-step explanation:

Consecutive interior angles are (supplementary angle) meaning that the sum of the consecutive interior angles is 180.

[tex]\sf 4x +5x=180^o[/tex]

[tex]\sf 9x = 180^0[/tex]

[tex]\sf \cfrac{9x}{9} =\cfrac{180}{9}[/tex]

[tex]\sf x=20^o[/tex]
