we are given

△ABC

we can use area of triangle formula

$A=\frac{1}{2} AB*BC*sin(B)$

we have

AB=6

BC=10

m∠B=120°

so, we can plug it

$A=\frac{1}{2} 6*10*sin(120)$

$A=\frac{1}{2} *60*\frac{\sqrt{3} }{2}$

$A=15\sqrt{3}$ ..............Answer

21 X .22= 4.6

Calculating the variance requires finding the product of 21 and 22%. To make this easier we convert 22% into it's decimal form and construct the equation. To back check this answer we can use 10% of 21 voters which equals 2.1% then double that amount to reach 4.2%, knowing that we now have a close approximation of the variance we can eliminate answers a, b, and d, leaving c as the only logical choice.</span>
