Question

I am crying pls answer this question​

Answer 1

Answer:

<E+<C+<EBC =180°

90°+<C+20°=180°

<C+110°=180°

<C=180°-110°

<C=70°

<C=<A (vertical opposite angle)

hence

<DAB and <BCD=70°

<A+<F+<B=180°

70°+90°+ <FBE=180°

150° +<FBE=180°

<FBE=180°-150°

<FBE=30°

Hence,

<FBE=30,<DAB=70°, <BCD=70°
