Answer:</h3>
- interior: 144°
- exterior: 36°
<h3>
Step-by-step explanation:</h3>
It may be easiest to remember that the sum of exterior angles of any convex polygon is always 360°.
Your decagon has a sum of exterior angles that is 360°. Since it is a regular 10-sided polygon, each one is 1/10 that value: 36°.
The measure of each exterior angle is 36°.
The measure of an interior angle is the supplement of the exterior angle. Each interior angle of the regular 10-sided polygon will be ...
... 180° -36° = 144°
The measure of each interior angle is 144°.
_____
A formula often used for the sum of the measures of the interior angles is ...
... interior angle total = (n -2)×180°
For a 10-sided figure, the interior angle total is ...
... (10 -2)×180° = 1440°
When this sum is divided into 10 equal angles, the measure of one interior angle is ...
... 1440°/10 = 144° . . . . . agrees with the above computation
The exterior angle measure is the supplement of this:
... 180° -144° = 36° . . . . . exterior angle measure; agrees with the above computation
Since 4 is only 2/3 of 6, then you need to divide 60 into 3rds.
1/3 of 60=20
60+20=80!
Hopefully this is correct, but i will go check real quick!

Hello!
To calculate how much the birdseed would cost per pound, we must divide the cost of 7 pounds ($15.89) by the number of pounds (7):
15.89 ÷ 7 = 2.27
Therefore, each pound of the birdseed costs $2.27.
Answer:
x = 4
Step-by-step explanation:
I'd suggest you write (1/24)x = 1/6 to avoid any ambiguity about the coefficient of x.
Multiplying both sides by 24 (the LCD) will eliminate the fractions:
24(1/24)x = 24/6, or x = 4.
