What is the point of E?

Circles $\Gamma_1$and $\Gamma_2$intersect at 2 distinct points $A$and $B$. A line $l$通过 $A$intersects $\Gamma_1$and $\Gamma_2$at points $C$and $D,$respectively, such that $C$is not in $\Gamma_2$and $D$is not in $\Gamma_1$. Point $E$is the intersection of the tangent to $\Gamma_1$at $C$and the tangent to $\Gamma_2$at $D$.

If $\ angle CBD = 71^\circ,$what is the measure (in degrees) of $\ angle CED?$
