Answer:
sin(B) = 2/3
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side.
sin(B)/b = sin(A)/a
sin(B)/8 = sin(30°)/6 . . . . fill in the given values
sin(B) = 8(1/2)/6 . . . . . . . .multiply by 8
sin(B) = 2/3
Answer:
2. (b) ∠ZYX
3. (b) noncollinear
Step-by-step explanation:
2. An angle is named by naming the two rays that make it up. The vertex (common end point of the two rays) is named in the middle.
Here, the rays making the angle are YX and YZ. The angle could be named either ∠XYZ or ∠ZYX.

3. Points not on the same line are <em>noncollinear</em>. Point E does not lie on line AB, so points A, B, and E are noncollinear.

I'm not sure what you're really talking about.
But I think you are talking about fractions.

The number that goes on the top is numerator.
area of the opening 14.93 sq. inch.
From this statement "the area of the opening may be expressed as the function: a(θ) = 16 sin θ ⋅ (cos θ + 1).
if θ = 30°
We can substitute 30° in the expression a(θ) = 16 sin θ ⋅ (cos θ + 1) to get the area of the opening.
The area of the opening = 16 sin 30 ⋅ (cos 30 + 1)
= 16x0.5 (0.866 + 1)
= 8(1.866)
= 14.93 sq. inch.
