Someone me ? ? with this explain to me

∠3 is congruent with 111°, because when both (are seperately) added to either ∠1 or ∠2, they will = 180°

Meaning they are both supplementary angles with either ∠1, or ∠2, making them congruent

So 69 degrees should be your answer

hope this helps

111 + angle 1 = 180 degrees   ( internal angles between parallel sides are supplementary)
So angle 1 = 180 - 111 = 69 

Angle 1  = angle 2  because this is an isosceles trapezium.

Therefore angle 2  = 69 degrees  (answer)

32.68 the is the !
