    angle AEC is 90, because BEC is 30 + BED= 60, whch means angle AEB=60 & 60+30=90

    the best thing is to first draw a picture. Unfortunately I can't here.

    since angle BEC=30, the CED also is 30. Now you know BED is 60, so AEB is 60. so add AEB to BEC and you will have AEC =90.

    EB is the bisector of <BED and given <BEC=30

    Therefore <BED=60

    again <AEB=60 ,EB bwubf th biawctor of <AED

    Therefore <AEC=<AEB+<BEC=60+30=90

    <CED = <BEC = 30

    So <BED = 60 = <AEB

    So <AEC = <AEB + <BEC

    = 60 + 30

    = 90

    BEC = 30

    BED = 60

    AEB = 60

    AEC = 90
