Answer 1

Answer:

13cm

Step-by-step explanation:

Solution

In ∆ABC, AM is median AB²+ AC² = 410

BC = 12

Find AM.

To Sol: In ∆ABC,

Mis

AM

Mid point of BC

Median,

then BM=CM

By using apollonius theslem,

AB²+ Ac² 2(BM²+ AM²) = 410 2 ((12) ²+ AM²) BM= = BC

410 2(6²+AM²)

⇒>> 410

2.36 +2 AM²

=> 410 = 72 + ZAM² = 2AM² = 410-72

2AM² = 338 =) AM² = 338 = 169 2 ⇒ AM² = 169 ⇒ AM² = 13² ⇒AM=13

:. The value of Hence AM 13cm The value of AM = 13cm option (B) is correct
