Question

The interior angles of an octagon abcdefgh are in ap.If the largest and the second largest have an angle of 153 degrees.Find the average of the least two??

Answer 1

Answer:

Step-by-step explanation:

the average of the least two angles will be 117 degrees and angles will be 114 and 120 degrees.

All angles will be

114,120,126,132,138,144,150,156.

smallest angle = 114

diff in angles = 6 deg

avg of largest and second largest angle = (150+156)/2= 153 deg

average of the least two = (114+120)/2 =117 deg

Hope it helps you...
