Length BC is opposite of angle A and AC is opposite of angle B. 

<span>Since we know one set of opposite angles and lengths and looking for the length where we know the opposite angle, we can use law of sines: </span>

<span>a / sin(A) = b / sin(B) </span>
<span>8 / sin(71) = b / sin(42) </span>
<span>b sin(71) = 8 sin(42) </span>
<span>b = 8 sin(42) / sin(71) </span>
<span>b ≈ 5.66 units (rounded to 2DP)</span>

28x^2-21x-16x+12

<u>2) Collect like terms</u>

28x^2+(-21-16x)+12

<u>3) Simplify</u>
