Answer:
The answer is B. 9
Use cosine rule. In this case, I am using SOH and the right triangle:
sin 60°= a ÷ 6 root 3
(6 root 3)(sin 60°)= a
a=9
Step-by-step explanation:
2* 10^4 would be bigger than 8* 10^3.
10^4 = 10000*2=20000
10^3 = 1000*8=8000
You would cancel the common factors in the numerator and denominator.
Exact Form:
2/9
