Question

AB and CD intersect each other at point E. ∠ABED= 145°, then find the measure of remaining angles.

Answer 1

<DEB= 145°.....GIVEN

SO, <AEC= 145°......VERTICALLY OPPOSITE ANGLES

<DEA=180-145=35°..........LINEAR PAIR

<BEC=35°.................VERTICALLY OPPOSITE TO <DEA

Answer 2

angle BEC is equal to 35 degree
