Answer:
128.57 degrees
Step-by-step explanation:
To find the measure of an interior angle of a regular polygon with sides, we can use the formula:
To find the measure of an interior angle of a polygon with 7 sides, all we have to do is plug in 7 into the formula:
7 minus 2 equals 5, so the answer is
÷
180 times 5 is equal to 900, and 900 divided by 7 is approximately 128.57
Answer:
x= -1/5y+9/5
Step-by-step explanation:
5x+y=9
Step 1
First you need to add -y to both sides, basically subtracting y
5x+y-y= 9-y
Step 2
Divide both sides by 5, or multiply by 1/5. You want to do this because to cancel out 5, so you multiply the reciprocal, or divide the constant.
1/5*5x=-y+9/5
Then, you will get the answer
