Answer:
m = 129°
Explanation:
Finding the unknown angle in the polygon:
Find the sum of angles of the polygon using the formula,
Sum of angles of polygon = (n - 2)*180
n is the number of sides. n = 6
= ( 6- 2) *180
= 4*180
= 720°
Sum of the angles of given polygon = 720
90 + 146 + 90 + 135 + m + 130 = 720
m + 591 = 720
m = 720 - 591
m = 129°
