Step-by-step explanation:
given :
- A (3,2), B (-4,-4) & C (5-8) are the verticles of a triangle
to find :
- the length of median through Vertex C = ?
Solution :
- vertices of traingle ABC
- A (3,2), B (-4,-4) & C (5-8)
- traingle ABC = √ (5+ 1/2 + ( -8 +1)
- traingle ABC = √121/4 + 49
- traingle ABC = √ 121+ 196/4
- traingle ABC = √317/2
hence, option C is correct none
