Answer:
N=55
Step-by-step explanation:
1. The equation for the Pythagorean theorem is [tex]a^2+b^2=c^2[/tex] . C refers to the hypotenuse (the longest side of the triangle, or the slanted part to make it easier). a and b are the legs (the side lengths)
2. plug the numbers in. It would be [tex]a^2+48^2=73^2[/tex]
3. This would then turn into [tex]a^2+2304=5329[/tex]
4. Subtract the 2304 on both sides. This should then get you [tex]a^2 = 3025[/tex]
5. Take the square root of both x^2 and 3025
6. You then get that a=55. (a would be N)
