Sum of the interior angles of a pentagon = 18(n-2); where n=5 > 180(3) = 540

x = (540 - (180+130))/2 = 115

Answer: E

sum of internal angle of pentagon = (n-2) * 180 = 3 * 180 = 540
sum ; 2x+130+180 = 540
x= 115
IMO E

Sum of angles in a polygon of n sides= (n-2)*180
Here, pentagon has n=5
So, 90+90+130+x+x=(5-2)*180=540
Hence, x=115
