Question

A wooden plate is shaped as a pentagon. The measure of one angle is 40°. The remaining interior angles are obtuse and of equal measure.

What is the measure of each obtuse angle in the pentagon?

a) 120°
b)125°
c)110°
d)100°

Answer 1

For a pentagon, the sum of angles = 540..

So given one angle = 40.. and remaining angles are equal..

so 4x + 40 = 540 --->> 4x = 500

x = 125 degree... option B..

Answer 2

for a polygon, get number of sides..

so number of angles = 180 * (n-2)

where, n = number of sides for polygon...
