Answer» 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 #666

Answer»

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
