Angles of a hexagon

Find the interior angles of a hexagon if the sizes of the angles form an arithmetic sequence, and the smallest angle is 70°.

Correct answer:

A =  70 °
B =  90 °
C =  110 °
D =  130 °
E =  150 °
F =  170 °

Step-by-step explanation:

A=70=70
s=180 (62)=720  A+B+C+D+E+F=s A+(A+d)+(A+2d)+(A+3d)+(A+4d)+(A+5d)=s 6A+15d=s=720  d=15s6 A=157206 70=20  B=A+d=70+20=90
C=B+d=90+20=110
D=C+d=110+20=130
E=D+d=130+20=150
