x = the first integer.

x + 2 = the second integer.

x + 4 = the third integer.

x + x + 2 + x + 4 = -45

Combine like terms.

3x + 6 = -45

Subtract 6 from both sides.

3x = -51

Divide both sides by 3

x = -17

x + 2 = -17 + 2 = -15

x + 4 = -17 + 4 = -13

The largest integer is -13

The measure of an exterior angle of a regular polygon is given below. Find the measure of an interior angle. Then find the numbe

FromTheMoon [43]

Answer:

Internal angle = $160^\circ$

Number of sides = 18

Step-by-step explanation:

Given that:

We have a regular polygon with number of sides unknown.

Measure of an exterior angle of the polygon = $20^\circ$

To find:

Measure of an interior angle and the number of sides of the polygon?

Solution:

Let us have a look at the relation of sum of external angles.

Sum of one internal angle and its corresponding external angle = $180^\circ$

Internal angle + external angle = $180^\circ$

Internal angle = $180^\circ$ - $20^\circ$ = $160^\circ$

Sum of all the external of a regular polygon = $360^\circ$

All the external angles will be equal because it is a regular polygon.

Let the number of sides = $n$

Therefore,

$n \times 20^\circ = 360^\circ\\\Rightarrow n = 18$

Therefore, the answers are:

Internal angle = $160^\circ$

Number of sides = 18
