Answer:
The correct answer is option 3.
Step-by-step explanation:
Given : ΔPQR, QM is altitude of the triangle
PM = 8
MR = 18
To find = QM
Solution :
PR = 8 + 18 = 26
Let, PQ = x , QR = y, QM = z
Applying Pythagoras Theorem in ΔPQR

..[1]
Applying Pythagoras Theorem in ΔPQM

..[2]
Applying Pythagoras Theorem in ΔQMR

..[3]
Putting values of
and
from [2] and [3 in [1].




z = ±12
z = 12 = QM ( ignoring negative value)
The length of QM is 12.

-x²+3 / x =
So, we need to think about this problem as either what we have to multiply x by to get the equation, and do long division
= 4x³- x +
