Here is another question its at the bottom of the picture

a. ZC = 13.5

b. ZA : AC = 2 : 1

Step-by-step explanation:

See the diagram of the triangle attached to the question.

a. {Concurrency of median theorem}

⇒{Substituting the value of ZA which is given}

⇒ {Multiplying both sides with }

⇒ ZC = 13.5 {By simplification} (Answer)

b. We have {Concurrency of median theorem}

⇒

⇒ {By distributive property of multiplication}

⇒

⇒

⇒ {Multiplying both sides with 3}

⇒ ZA = 2 AC

⇒ ZA : AC = 2 : 1 (Answer)
