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!
83 kg converted to stones is 13 stones.
Step-by-step explanation:
Given,
We have to convert 83 kg to stones.
As it is given,
1 kg = 2.2 pounds
83 kg = 2.2*83 pounds
83 kg = 182.6 pounds
Now,
14 pounds = 1 stone
1 pound = 
182.6 pounds = 
182.6 pounds = 13.04 stones
Rounding to one dp
182.6 pounds = 13.0 stones
83 kg converted to stones is 13 stones.
