x^2 = 2^2 + 3^2
 x^2 = 4 + 9 = 13
so
hypotenuse = x = √13

hope that helps

To find out the missing leg of a right triangle, you have to use the Pythagorean Theorem which is a^2 + b^2 = c^2. C is the hypotenuse. So, substitute the numbers into that equation.

2^2 + 4^2 = x
4 + 16 = x
20 = $\sqrt{x}$

$T=xd+ym\\x(4)+y(100)=(120)\\x(1)+y(240)=(80)\\\\4x+960y=320\\4x+100y=120\\860y=200\\y=\frac{200}{860}\\y=\frac{10}{43}\\\\x+240(\frac{10}{43})=80\\x+\frac{2400}{43}=\frac{3440}{43}\\x=\frac{1040}{43}$

x = 1040/43 = $24.19 per day.

y = 10/43 = $0.23 per mile.
