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

Answer:
4,560
Step-by-step explanation:
When you do it you move the decimal to how many zeros you have. So you start at the decimal and move it three times.
Answer:
x=+-√10+3
Step-by-step explanation:
x^2=6x+1
x^2-6x=1
To create a trinomial square on the left side of the equation, find a value that is
equal to the square of half of b
a is the number next to x^2
b is the number next to x
c is the last number
b is -6
half of b is -3
square of half of b is 9
put 9 on both sides of the = sign
x^2-6x+9=1+9
x^2-6x+9=10
(x-3)^2=10
take the square root of both sides of the = sign
√(x-3)^2=√10
x-3=√10
x=+-√10+3
Step 1: Write down the decimal divided by 1.
