# 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°.

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

### Step-by-step explanation:

$A=70=70\text{°}$
$C=B+d=90+20=110\text{°}$
$D=C+d=110+20=130\text{°}$
$E=D+d=130+20=150\text{°}$
