Answer:

3 and 2. (or -2 and -3)

Step-by-step explanation:

With a little trial and error with whole numbers that differ by 1, we find that 3 and 2 works. 3^2 + 2^2 = 13 and 3-2=1.

vaieri [72.5K]

Answer:

125 m

Step-by-step explanation:

The path of Kristina is in the shape of a right triangle where, the perpendicular is the path from the McDonalds to the three-way junction which is 145 m and the shortest distance between the McDonalds and the church is 191.442 m.

By Pythagoras theorem

$145^2+x^2=191.442^2\\\Rightarrow x=\sqrt{191.442^2-145^2}\\\Rightarrow x=125\ \text{m}$

Christina had to travel 125 m from the three-way junction to the church.
