Find the sun of the interior angles for each polygon
sergeinik [125]

Answer:

360

1080

Step-by-step explanation:

We can find the sum of the interior angles of any regular polygon by using this formula

(n - 2) * 180

where n = number of sides

For the square: the square has 4 sides

To find the sum of the interior angles we simply substitute 4 for n in the formula

Formula: (n - 2) * 180

Substitute 4 for n

(4 - 2 ) * 180

Subtract 4-2

2 * 180

Multiply

= 360

The sum of the interior angles of the first polygon is 360

For the second one:

We will repeat this exact process the only difference is the value of "n"

The polygon shown has 8 sides

So to find the sum of the interior angles we simply substitute 8 for n in The formula

Formula (n - 2) * 180

Substitute 8 for n

(8 - 2) * 180

Subtract 8 - 2

6 * 180

Multiply

= 1080

The interior angles of a 8 sided figure will add up to 1080

Two jets simultaneously started traveling in opposite directions from the same airport. Four hours later they were 3800 miles ap
Basile [38]

Step-by-step explanation:

the slower plane traveled x miles in 4 hours.

the faster plane traveled x + 4×80 = x + 320 miles in 4 hours.

so,

x + x + 320 = 3800 miles

2x =3480 miles

x =1740 miles (in 4 hours) .

that means the slower plane's speed was 435 mph.

and the faster plane's speed was 435 + 80 = 515 mph.

7. Find the measure of the angle of elevation of the sun when a boy 5 feet tall cast's a shadow
Alecsey [184]

Answer:

45\degree

Step-by-step explanation:

We use trigonometry to find the angle of elevation.

From the diagram, the angle of elevation of the sun is \angle A

Recall the mnemonics SOH CAH TOA.

\tan A=\frac{Opposite}{Adjacent}

\tan A=\frac{5}{5}

\tan A=1

A=\tan^-1{1}=45\degree

Therefore the angle of elevation of the sun is 45\degree
