Question

If A(5,4 ) , B (-3 , -2) and C (1 -8) are the vertices of a ∆ . Segment

AD is median. Find the length of seg AD:​

Answer 1

Answer:

$Length of AD = \sqrt{117}$

Step-by-step explanation:

Coordinate of point D is {(-3+1)/2,(-2-8)/2} = (-1,-5)

$Length of AD \: = \sqrt{ {(5 - ( - 1)) }^{2} + {(4 - ( - 5))}^{2} } = \sqrt{ {6}^{2} + {9}^{2} } = \sqrt{36 + 81} = \sqrt{117}$
