In the △pqr, pq = 39 in, pr = 17 in, and the altitude pn = 15 in. find qr.

Answer : The value of side QR is, 44 in.

Step-by-step explanation :

As we know that an altitude of a triangle is a segment from a vertex to the line containing its opposite side, and is perpendicular to that line.  

First we have to determine the side QN.

Using Pythagoras theorem in ΔPNQ :

Given:

Side PQ = 39

Side PN  = 15

Now put all the values in the above expression, we get the value of side QN.

Now we have to determine the side RN.

Using Pythagoras theorem in ΔPNR :

Given:

Side PR = 17

Side PN  = 15

Now put all the values in the above expression, we get the value of side RN.

As,

Side QR = Side QN + Side RN

Side QR = 36 + 8

Side QR = 44

Thus, the value of side QR is, 44 in.

honestly bro aint no one got time to answer these dumb question just do it p***y
