The diagonal (hypotenuse) is 13 in.
You need to use the Pythagorean Theorem
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%2B%20%7Bb%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D%20)
then just plug in the numbers and solve for c.
![{12}^{2} + {5}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7B12%7D%5E%7B2%7D%20%2B%20%7B5%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D%20)
![\sqrt{169} = c](https://tex.z-dn.net/?f=%20%5Csqrt%7B169%7D%20%3D%20c)
13 = c
Let the unpaid balance amount be represented by = x
Rate of interest is = 1.9 %
Stephen paid an amount of = $21.77
This 21.77 is the amount of 1.9% of x
So, ![\frac{1.9x}{100}=21.77](https://tex.z-dn.net/?f=%5Cfrac%7B1.9x%7D%7B100%7D%3D21.77)
![1.9x=2177](https://tex.z-dn.net/?f=1.9x%3D2177)
x = 1145.789 or rounding it we get 1145.79
So, the unpaid balance of Stephen Joyce is $1145.79
