Answer:


\boxed{\bf x = 1 {8}^(o) }

Explanation:

In the given figure....


\boxed{\bf m\angle BOA = 9 {0}^(o)}


\bf m\angle BOA + m\angle COA = 9 {0}^(o)


  • \bf 4x + x = 9 {0}^(o)

Combine like terms. 4x + x = 5x


  • \bf 5x=90

Divide both sides by 5.


  • \bf \cfrac{5x}{5} = \cfrac{90}{5}

  • \boxed{\bf x = 1 {8}^(o) }
