We know that
cos 45°=√2/2------> equation 1
in the triangle
cos 45°=m/(9√2)----> equation 2
equals 1 and 2
so
√2/2=m/(9√2)---> 9√2*(√2)=2*m-------> 9*2=2*m-------> m=9
the answer is
m=9 units
Hey mate!
You stuck?
Xian and Kai would both need to receive stamps for 6 months to eventually have the same amount of stamps.
Xian: 12 stamps from club x 6 months + 56 stamps = 128
Kai: 8 stamps from club x 6 months + 80 stamps = 128
Hope this helps! :)

1.2*2= 2.4 (20%)
1.2/2= 0.6 (5%)
2.4+0.6= 3
12+3= $15
