Jambmaths question:
The angles of a polygon are given by x, 2x, 3x, 4x, and 5x respectively. Find the value of x
Option A:
24o
Option B:
30o
Option C:
33o
Option D:
36o
Jamb Maths Solution:
The polygon is 5 – sided polygon. The total interior angle of a polygon is given as $(n-2){{180}^{\circ }}$So when n = 5The total interior angle is $(5-2){{180}^{\circ }}={{540}^{\circ }}$Therefore,$x+2x+3x+4x+5x={{540}^{\circ }}$$15x={{540}^{\circ }}$$x=\frac{{{540}^{\circ }}}{15}={{36}^{\circ }}$
