answer is A. first one
A decagon has 10 sides.
The sum of the interior angles is found using the formula S = (n-2)*180, where n is the number of sides.
The total sum of the interior angles of a decagon would be:
(10-2) *180 = 8 * 180 = 1440 degrees.
Now to find the measure of each interior angle, divide the total sum by the number of sides:
1440 / 10 = 144
Each angle is 144 degrees.
Add 5 and eliminate parentheses
... y = -2x +6 +5
Simplifying, you get
... B. y = -2x +11
Answer:
12=34+45
Step-by-step explanation:
34+12=34
Multiply by 2 which is 8x-8y=-80then subtract from 8x-8y=80 you will get 0=160 so that it is no solution. Have a nice day.
