The lengths of the sides are 7, 23 and 24.
In order to find this, we need to add all of the side lengths together and set equa to 54. This will allow us to solve for n.
n + 3n + 2 + 4n - 4 = 52
8n - 2 = 52
8n = 54
n = 7
This gives us the length of the first side. To solve for the others, plug 7 into the equations.
3n + 2
3(7) + 2
21 + 2
23
Then the next one.
4n - 4
4(7) - 4
28 - 4
24
I believe by my math that Celsuis = 20°
About 53.98 you have to do 44.99 times .20 then add that number to the 44.99
Y=z/x
for the second case y₁=(z/3)/3x =(z/x)*(1/9) =y/9
thus answer is A
