since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°
so the angle WOP = 45°
now drawing a imaginary line which seperates the triangleWOP into half
so the angle of imaginary line is 45/2 = 22.5
sin(theta) = opp/hyp
since WP (opp) is unknown. take as x
sin(22.5) = x/44
0.383×4 = x
x = 1.532 (app) = 1.5 cm
perimeter = 1.5 × 8
= 12 cm
area of triangle WOP = 2×1/2 ×bh = bh
= 4×1.5
= 6 cm²
so the area of regular polygon = 8× area of a triangle
= 48 cm²
B because the variable (x) is not raised to any power.
3 decimal places. You start with the number with the two decimal places and then you add a decimal place because the number you're multiplying it by has one decimal place.
Answer: 
Step-by-step explanation:
When the scientists detect a signal frequency from the ocean floor, then the depth of submarine =
feet
=
feet
When they dive farther to check the signal, then the depth of the submarine=
feet.
The net change in their elevation =
