Answer: 360°

Step-by-step explanation:

The sum of the exterior angle of a polygon is always 360°

Or, From the sum of the interior angle of a polygon,

(2n - 4)× 90° where n = 8

(2 × 8 - 4) × 90 =

16 - 4 × 90

12 × 90 = 1080°

Now each interior angles of the polygon

= 1080/8

= 135°.

Now, to find each exterior angle of the polygon,

= 180°- 135°

= 45°

To find the exterior angle now, we multiply 45° by eight

= 45° × 8

= 360°

Need help with 2 and 3 and express I’m radical form
kondaur [170]
This is just simple Pythagorean’s theorem. a^2 + b^2 = c^2

Number 2:
5^2 + x^2 = 10^2
25 + x^2 = 100
x^2 = 75
x = sqrt 75 = 5*sqrt(3)

Number 3:
4^2 + x^2 = 7^2
16 + x^2 = 49
x^2 = 33
x = sqrt 33

In January Jennifer was allowed to use 150 text messages. If she is allowed to use the same amount of text messages every month.
Firlakuza [10]

She would have used 1200 messages in all by the month of August.

Step-by-step explanation:

Messages allowed per month = 150

There will be 8 months starting from January to August, therefore,

Time period = 8 months

Messages in 8 months = Messages per month * Time period

Messages\ in\ 8\ months=150*8\\Messages\ in\ 8\ months=1200

She would have used 1200 messages in all by the month of August.

3 An open cone has a vertical angle measuring 40°
belka [17]

Answer:

13.41 cm

Step-by-step explanation:

The radius, height, and HALF of vertical angle makes a triangle.

Where

Radius will be the base of the triangle

Height will be the "height" of the triangle

Top angle will be HALF of vertical angle (40/2 = 20)

From the 20 degree angle, the side "opposite" would be the radius, which is 30. The side "adjacent" would be the height, let it be h.

<em>Which trig ratio relates opposite and adjacent? Yes, that is TAN. Thus we can write:</em>

Tan(20) = opposite/adjacent

Tan(20) = 30/h

h = 30/Tan(20)

h = 13.41

So

The height of the cone would be around 13.41 cm
