Answer:
Step-by-step explanation:
cosine law
a²=b²+c²-2(bc)cos44 (c=20, b=15)
a²=15²+20²-2(15*20)cos44
a=√15²+20²-2(15*20)cos44
a=13.91
Let, the number = x
x/3 + x = 16
x+3x /3 = 16
4x = 16*3
x = 48/4
x = 12
So, the number would be 12
Hope this helps!
It is 1024 i believe. 16^3/4 = 1024
88.2 is your answer, have a nice day
