Answer:
11 or 18 either one if im wrong sorry
Step-by-step explanation:
The area of a regular hexagon with an apothem 18.5 inches long and a side 21 inches is 1, 165. 5 In²
<h3>
How to calculate the area of a regular hexagon</h3>
The formula is given thus;
Area of hexagon = (1/2) × a × P
where a = the length of the apothem
P = perimeter of the hexagon
Given a = 18. 5 inches
Note that Perimeter, p = 6a with 'a' as side
p = 6 × 21 = 126 inches
Substitute values into the formula
Area, A = 1 ÷2 × 18. 5 × 126 = 1 ÷2 × 2331 = 1, 165. 5 In²
Thus, the area of the regular hexagon is 1, 165. 5 In²

Answer:
third option
Step-by-step explanation:
m(n(x)) =
the domain of this is R/(4)
so as the third option
The answer is B. You can find this by turning 3/4 into a decimal, which is .75. You can then divide .75 by 6 to get 0.125 (which is the decimal form of 1/8).
Answer:
24
Step-by-step explanation:
angle = 38
opposite of angle = 15
hypotenuse = c
sohcahtoa
sin utilizes both opposite and hypotenuse
thus,
sin(38) = 15/c
multiply both sides by c to make it a numerator
csin(38) = 15
divide both sides by sin(38) to get c
c = 15/sin(38) ≈ 24
