Q. 6 F5.0( 1 Vote )

Fill in the blanks so that the following statements are true:

In ΔABC, A—M—B, A—N—C and ||. If AM = 8.4, AN = 6.4, CN = 19.2, then AB = ______.

Answer :

We have



Given: A – M – B, A – N – C


MN BC


AM = 8.4


AN = 6.4


CN = 19.2


To find: AB = ?


Take ∆ABC,


We know that, MN BC. So, by property we can write as:






BM = 25.2


We know AM = 8.4 and BM = 25.2.


Now, AB = AM + BM [, from the diagram]


AB = 8.4 + 25.2


AB = 33.6


Thus, the answer is 33.6.
