Answer:
540 = (r+s)*3 = (r-s)*6
3r + 3s = 6r - 6s
9s = 3r
3s = r
540 = (3s+s)*3
540 = 12s
s = 45
r=135

Answer:
b
Step-by-step explanation:
If you multiple each side by 3 then they will equal the numbers that b has
We know that
applying the law of cosines
c²=a²+b²-2*a*b*cos C
in this problem
a=10 m
b=11 m
c=13 m
C=?
c²=a²+b²-2*a*b*cos C----> cos C=[a²+b²-c²]/[2*a*b]
cos C=[10²+11²-13²]/[2*10*11]----> cos C=0.2364
C=arc cos (0.2364)----> C=76.33°
the answer is
76.3°
