Parallel Lines and Angle Measurement

10. [BA // [CD

$m(\widehat{ABF}) = m(\widehat{ECF})$

$m(\widehat{FCD}) = m(\widehat{EBF})$

$m(\widehat{BFC}) = 70^{\circ}$

$m(\widehat{BCE}) = 25^{\circ}$

Yukarıdaki verilere göre, $m(\widehat{CBE})$ kaç derecedir?

Soruda görsel içerik var: The image displays a geometric figure with two parallel rays [BA and [CD. Ray [BA points to the right, and ray [CD points to the right, positioned below it. Point B is on the top ray, and point C is on the bottom ray. A line segment connects B and C vertically. Inside, points E and F are connected to B and C, creating various angles. Specifically, there are lines connecting B to F, C to F, B to E, and C to E. The angle m(BFC) is 70 degrees. The angle m(BCE) is 25 degrees. There are angle equalities: m(ABF) = m(ECF) and m(FCD) = m(EBF). Several angles are marked with variables 'x', 'y', and 'alpha'.
