Question

I need help plssss..

Answer 1

6x+42°=180°(ANGLES ON A STRAIGHT LINE)

$6x = 180 - 42 \\ 6x = 138 \\ \frac{6x}{6} = \frac{138}{6} \\ x = 23$

IF DF IS PERPENDICULAR TO AC IT MEANS m<DBC =90°

IF DF IS PERPENDICULAR TO AC IT MEANS m<DBC =90°m<DBE+m<EBC= m<DBC

IF DF IS PERPENDICULAR TO AC IT MEANS m<DBC =90°m<DBE+m<EBC= m<DBCm<DBE+18°=90°

IF DF IS PERPENDICULAR TO AC IT MEANS m<DBC =90°m<DBE+m<EBC= m<DBCm<DBE+18°=90°m<DBE =90°-18°

IF DF IS PERPENDICULAR TO AC IT MEANS m<DBC =90°m<DBE+m<EBC= m<DBCm<DBE+18°=90°m<DBE =90°-18°mDBE=72°

Hope THIS helps
