Answer:

3a. The polygon has 15 sides, so it is a pentadecagon or a 15-gon.

3b. Each interior angle measures 156°.

3c. The measure of an exterior angles is 24°

Step-by-step explanation:

(n - 2)180 = 2340

n - 2 = 13

n = 15

The polygon has 15 sides, so it is a pentadecagon or a 15-gon.

2340/15 = 156

Each interior angle measures 156°.

There are 2 ways to calculate the measure of an exterior angle.

Method 1:

Each exterior angle is supplementary to its adjacent interior angle.

156 + x = 180

x = 24

Method 2:

The sum of the measures of the exterior angles of a polygon, 1 per vertex, is 360, no matter the number of sides.

360°/15 = 24°

The measure of an exterior angles is 24°

Pls help With this question thank you

Answer:

$CD=4 \text{ cm }$

Step-by-step explanation:

We have a similarity of triangles. Once the side BC and ED are parallel,

$\frac{BC}{AC} =\frac{ED}{AD}$

$\frac{10}{AC} =\frac{5}{4}$

Once $AC=AD+CD \Rightarrow AC=4+CD$

$\frac{10}{4+CD} =\frac{5}{4}$

$5CD+20=40$

$5CD=20$

$CD=4 \text{ cm }$

Answer:

$\frac{5x^{2} }{12}$

Step-by-step explanation:

Given: Height: x

Base: $\frac{5x}{6}$

Now, finding the area of triangle.

Formula; Area of triangle= $\frac{1}{2} \times base\times height$

⇒ Area of triangle= $\frac{1}{2}\times \frac{5x}{6} \times x$

⇒ Area of triangle= $\frac{5x^{2} }{12}$

Hence, area of triangle= $\frac{5x^{2} }{12}$
