Answer:
x=53
Step-by-step explanation:
pythagoras theorem
a^2 + b^2 =c^2
here a and b are two small sides and c is hypotenuse (longest side)
28^2 + 45^2 = c^2
784 + 2025 =x^2
2809 =x^2
=x
53 =x
Perimeter: 36
5n + 3 = 36
5 · 6.6 + 3 = 36
N = 6.6
------------------------------------------
Perimeter: 36
1/4n + 2 = 36
1/4 · 136 + 2 = 36
N = 136
Hopefully i understood the question correctly :) Hope this helps
