Find the area of the regular figure below:
A) 414.5 ft2
B) 421.3 ft2
C) 425.1 ft2
D) 432.9 ft2
E) 443.4 ft2

pls show work

E. 443.4 ft²

Step-by-step explanation:

Since it is a regular triangle, it means all three sides are of equal lengths and all angles are of the same degree measure.

Therefore, all sides = 32 ft each

Each equal angle = 60° (sum of all angles = 180)

The area of the triangle can be calculated using the formula, ½*a*b*sin(C),

Where,

a = 32 ft

b = 32 ft

C = 60°

Plug in the values

Area = ½*32*32*Sin(60)

Area = 443.4 ft² (nearest tenth)

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is
