The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)
<h3>Trigonometric Ratios</h3>
From the given triangle ABC, we see that;
∠A = 66°
∠C = 38°
AB = 3
Thus using sine rule, we have;
AB/sin C = BC/sin A
3/sin 38 = BC/sin 66
BC = (3sin 66)/sin 38
BC = 4.45

180º (-180º): (x, y) ---> (-x, -y)
270º (-90º): (x,y) ---> (-y, x)
Just think of the half of your number (Thinking of pizzas or pie helps) Ex:
Half of 10 is 5
Another way to word that is
10
None because they both equal the same number
