Answer:

162,162,18,18

Step-by-step explanation:

each two opposite angles are equal

since there is an angle equals 162° then the opposite angle equals 162°

since the sum of all angles equal 360°

360-(162+162)= 36

so the sum of the other two opposite angle = 36 then the measure of one angle =36/2 =18°
