1.you could put that FHG is 90 degrees and that it is a right angle.
2.you could put that FEG is half a right angle and it is 45 degree angle
*hope this helps....i try my best to answer this
Let x = 1st positive integer
Let x + 1 = 2nd positive integer
As give, their sum of squares is 841
![x^{2}+(x+1)^{2}=841](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B%28x%2B1%29%5E%7B2%7D%3D841)
![x^{2}+x^{2}+2x+1=841](https://tex.z-dn.net/?f=x%5E%7B2%7D%2Bx%5E%7B2%7D%2B2x%2B1%3D841)
![2x^{2}+2x+1=841](https://tex.z-dn.net/?f=2x%5E%7B2%7D%2B2x%2B1%3D841)
![2x^{2}+2x-840=0](https://tex.z-dn.net/?f=2x%5E%7B2%7D%2B2x-840%3D0)
factor 2 out, ![x^{2}+x-420=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2Bx-420%3D0)
![x^{2}+21x-20x-420=0](https://tex.z-dn.net/?f=x%5E%7B2%7D%2B21x-20x-420%3D0)
![x(x+21)-20(x+21)=0](https://tex.z-dn.net/?f=x%28x%2B21%29-20%28x%2B21%29%3D0)
(x+21)(x-20)
This gives, x=20 and =-21 (neglect the negative value)
So, x = 20
x+1 = 21
So, the two numbers are : 20 and 21
Answer:
I think it should be: P = (85-71)/(85-66) = 14/19
