Question

The measure of an octagon is twice that of the other seven angles. What is the measure of each angle?

Answer 1

let the angle of an octagon be x

now we know that in an octagon a+b+c+d+e+f+g+h=360 sum of angles

now we have 2x+x+x+x+x+x+x+x=360

9x=360

x=40 i hope this is correct....

Answer 2

The measure OF ONE ANGLE of an octagon is twice that of the other seven angles....
