I believe x is equal to five. Try it. Hope this helps mate.
Answer:
R, T, S
Step-by-step explanation:
R+S+T=180 degrees
9x-2+4x+36+5x+20=180
18+54x=180
54x=162
x=3
R=9*3-2 (substitute x with 3)
R=25
S=4*3+36
S=48
T=5*3+20
T=35
Shortest to longest: R, T, S
16 square kilometers is 3953.6861 acres.
154/10=15.4. Then apply greatest integer function (smallest integer larger than that number) to get 16.
