    Lable G so that GCE is a diameter. The arc(DE)=124 so that arc(DG)=56.
    Therefore angle(DEC)=28.

    angle BDC=90 .......... radius is perpendicular to tangent at point of contact

    angle EDC= 90-62=28

    angle DEC=angleEDC=28 ............................. since DC=CE

    angle CEF= angleDEF-angleDEC=62-28=34
