Question

What is the angle BCE ?​

Answer 1

Answer:

∠ BCE = 80°

Step-by-step explanation:

∠ BCD = ∠ ABC = 35° ( alternate angles are congruent )

∠ DCE and ∠ CEF are same- side interior angles and supplementary, thus

∠ DCE + ∠ CEF = 180° , that is

∠ DCE + 135° = 180° ( subtract 135° from both sides )

∠ DCE = 45°

Thus

∠ BCE = ∠ BCD + ∠ DCE = 35° + 45° = 80°
