In a triangle MNO with altitude NP with MP of 15 and NP of 9 what is the length of PO? MNO creates a right angle!

    M 15
    z P
    9 x
    N y O

    I sketched your triangle and concluded that the right angle must be at N
    It is easy to show that
    triangle MPN ≈ triangle NPO
    then MP/PN = PN/PO
    15/9 = 9/PO
    15PO = 81
    PO = 81/15 = 27/5
