Answer:

Step-by-step explanation:
It is given that AC:CM = 3:4.
Therefore, let AC = 3k and CM = 4k
It is given that Δ ACM is right angled.
Therefore,




AM = 5k
But, AM = MP + AP
Therefore, MP + AP = 5k --- (1)
It is given that MP - AP = 1 --- (2)
Multiply (1) and (2), we get.
(MP + AP)(MP - AP) = 5k × 1 = 5k

Add and subtract
on the left side.

--- (3)
But, since CP ⊥ AM, Δ CMP and Δ CAP are right triangles. Therefore,
and

Now, (3) becomes,



7k = 5 or

AM = 5k
