Find the area of this regular polygon round to nearest tenth

Bezzdna [24]

Answer:

$A=163.9in^2$

Step-by-step explanation:

Let's use the regular polygon area formula when given the radius.

$A=\frac{(r^{2})(n)sin(\frac{360}{n})}{2}$

r is radius

n is the number of sides

Let's plug in the proper values into this equation and simplify:

$A=\frac{(7.74^{2})(7)sin(\frac{360}{7})}{2}$

$A=\frac{(59.9076)(7)(0.78183148)}{2}$

$A=\frac{327.86353299}{2}$

$A=163.93176649$

Given that is the angle bisector of A, determine the length of x. (SHOW YOUR WORK PLEASE!!!)

Sunny_sXe [5.5K]

The length of x will be 4 cm if is the angle bisector of A.

<h3>What is an angle bisector?</h3>

A straight line that splits an angle in a triangle into two congruent angles is known as the angle bisector.

Given sides;

AB=12

AE=8

BD=6

DE=x

From the triangle angle bisector theorem;

$\rm \frac{BD}{DE} = \frac{AB}{AE} \\\\ \frac{6}{x} =\frac{12}{8} \\\\ x=4$

Hence the length of x will be 4 cm.

the oval track below is formed by a straight section on each side and a semicircle at each end. what is the approximate distance

nikklg [1K]

Answer:

1040

Step-by-step explanation:

Circumference of the Circle: 439.82

Add that to the length of the rectangle time two: 439.82+(300x2)

That will give you the perimeter around the entire track:

439.82+(300x2)

439.82+600

1039.82

Rounded that is: 1040
