Question

ABC is a triangle. M and N are points on AB and BC respectively. If AB = 10cm, BM = 5cm, CN = 8cm and MN is parallel to AC then: * 1)BC = 10cm and BN = 8cm 2)BC = 16cm and BN = 5cm 3)BC = 16cm and BN = 8cm 4)BC = 10cm and BN = 5cm

Answer 1

Answer:

Hello There,

This is your answer.

Step-by-step explanation:

Given:

AB = 10 cm

BM = 5 cm

CN = 8 cm

MN is parallel to AC

Solution:

BC = 16 cm ( N is the midpoint of BC. CN = BN = 8 cm.

BC = CN + BN = 8 + 8 = 16 cm )

BN = 8 cm ( N is the midpoint of BC. CN = BN = 8 cm.)

Therefore, option 3) BC = 16 cm and BN = 8 cm is the correct option.
