why do you hate hannah?
so angle BAE would be 135
and then 180-135 = 45 would be the angle PAB
you can work out the exterior angle, we know exterior angles of polygons add up to 360 so 360/8=45
So, for an octagon, n=8, so So, there are 1080 degrees inside an octagon, which has 8 interior angles, so
So, each interior angle of an octagon is 135 degrees.
The line AE is bisecting (cutting in half) the octagon, so the angle EAB is half of 135, which is 67.5 degrees.
Since PAE is a straight line, there are 180 degrees on that line, so
I think your answer would be that
Think this should have helped. Tell me if some bits don't make sense, or you do not understand.
Since it is a regular octagon, each interior angle is 135 degrees - (n-2) x 180 = 1080; 1080/8 = 135
The line passes through points A and E, meaning that it creates a line of symmetry on either side.
Thus, angle BAE is simply 67.5 degrees (135 divided by 2)
Finally, angles on a straight line equate to 180 degrees - which means y=180-67.5 = 112.5 degrees
Soooooooo... THE ANSWER IS 112.5 degress
8 -2 x 180 degrees = 1080 degrees
only need angle HAB so we do 1080 degrees / 8 = 135 degrees
SO THE MIDPOINT OF HAB IS 67.5 degrees
TO FIND y WE SIMPLY TAKE 62.5 AWAY FROM 180
THIS IS BECAUSE ALL ANGLES IN A TRIANGLE ADD TO 180 DEGREES
THIS GIVES A FINAL ANSWER OF 112.5 ----- just finished my yr 11 maths exams and faced the 2015 ed excel maths paper so trust me on this answer LOL
p.s why are you doing maths work in the holidays :-o
