Question

please give me correct answer then you can give a correct so I Mark. you brainliest answer​

Answer 1

Answer:

40 Degree

Step-by-step explanation:

Draw a parallel line to AB and DE through C . Lets say FCG( F on left side) . Then by parallel line property angle BCF = 80degree and angle DCG= 60 degree . Now from sum of angle property on a single line . angle BCD+ BCF+DCG=180 degree . so angle BCD=40 degree

Answer 2

Answer:

constrruct a line parallel to AB

let line be fg

Step-by-step explanation:

we know that angles on the same side of a transversal equals to 180

so Ang ABC +Bcf =180

BCF =180-100

BCF=80

:.CDE+DCG=180

120+DCG=180

DCG=60

now BCF+BCD+DCG=180(LINEAR PAIR )

80+BCD+60=180

140 +BCD=180

BCD=40

actually u have to make a diagram ,,,,it will better make u able to understand
