Question

HELP!!! I will fan and give medals. I have 10 questions.

Answer 1

What is the measure of each interior angle of a regular octagon? (1 point)
A. 135
B. 1080
C. 147
D. 124

Answer 2

Find the value of a and y.
A. x= 109, y=108
B. x=108, y=109
C. x=108, y=108
D. x=109, y=109

Answer 3

Question 1 :
there is a formula for this..
(180n - 360) / n --- for an octagon, n would be 8
do the math and it will tell you the measure of each angle

Answer 4

So it would be c.?

Answer 5

Question 2:
formula for sum of interior angles..
sum = 180(n - 2) -- n = the number of sides, there are 4. Once you find the sum, subtract all of the other angles from it to get your answer for x.

for y.....71 + y = 180...solve for y

first one is not C...try again, just sub into the formula I gave you

Answer 6

Okay I re-worked one and got B, I used what you gave me, and for the second one I got y=109
