Answer:

x=(b+ac)/(2c-ab)

Step-by-step explanation:

Cross multiply:

2xc-ac=abx+b

Move the values with x to one side:

2xc-abx=b+ac

Factor out x:

x(2c-ab)=b+ac

Divide:

x=(b+ac)/(2c-ab)

In the △PQR, PQ = 39 in, PR = 17 in, and the altitude PN = 15 in. Find QR.
Licemer1 [7]

Answer:

So, this triangle PQR can be broken into two right triangles, PNQ and PNR, with legs PQ = 39, PN =15, and QN = ? and PR = 17, PN = 15, and NR =? respectively.


Let's solve for what is easier first:

Since we know that 5-15-17 is a Pythagorean triplet, we can infer that NR is 5....like I said earlier, it is a right triangle, so this guess holds true.


Here comes the interesting part:

Now, we have one part of QR, which is QN.

The other part can be solved by using the Pythagorean theorem.

It is (39^2-15^2)^(1/2)..which gives you 36, the square root of 1296, which happens to be the difference between the squares of 15 and 39.

SO, QR = QN + NR

5+36 = 41

QR = 41.

Hope this helps!
