where
n is the number of sides of the polygon
step 1
Find the sum of the interior angles in the given polygon
we have

substitute

step 2
Find the value of x
we know that

solve for x


step 3
Find the measure of each interior angle
substitute the value of x
Angle A

Angle B

Angle C

Angle D

Angle E

Answer:
0.02

Hope this helps!
The answer is 3
Multiply 6 by 3 to get the total amount of money for the books then minus the answer 18 which you get from 6 x 3 = 18
Then minus 18 from 21 to get $3
21 - 18 = 3
Answer:
x > 3
Step-by-step explanation:
This is based on the concept 'when a negative number is multiplied to both sides of the inequality, the sign gets reversed. For example, x > - 2 when it is multiplied by - 1, it becomes - x < 2.'
*only when the number is -ve.
Similarly, in this question, multiply both sides by - 1.
2x > 6
x > 6/2
x > 3
For more : take - 5 > - 2, as you know
Note that 5 is actually greater than 2. To make this true we change signs
