Question

in ∆ABC, AB=10,∆AC=7,BC=9 then find the length of the median drawn from point C to side AB.

Answer 1

Answer:

Length of median is √56 .

Step-by-step explanation:

The given data :-

i) AB = 10  

ii) BC = 9

iii) Let the  D be the point on AB and CD is median.

We have to find the length of CD

$AD = BD = \frac{AB}{2} = \frac{10}{2} = 5$

Consider the triangle BDC and applying pythagorus theoram.

$CD = \sqrt{BC^{2} - BD^{2} }$

$CD = \sqrt{9^{2}-5^{2} }$    = $\sqrt{81 - 25}$

CD = √56

Hence the length of median is √56 .

Answer 2

No His answer is wrong

the real answer is

$2 \sqrt{10}$
