Question

10. What is the measure of Angle a if the other angles are given? Name the polygons
b)71°,137°,130°,142°,a,150°​

Answer 1

Step-by-step explanation:

there are total 6 angle means total no. of sides be 6

a polygon with 6 side known as hexagon

sum of all angle of polygon = 180(n-2)

{here n is no. of side}

sum of all angle of hexagon = 180(6-2)

sum of all angle of hexagon = 180×4 = 720

71+137+130+142+a+150= 720

a+630= 720

a= 90
