Three angles are supplementary. ∠ACB=x+15° , ∠BCD=x+48°, ∠DCE=13°. What is the value of ∠BCD

Question

A: 80°

B: 100°

C: 52°

D: 67°

Answer 1

C: 52°

Answer 2

uncle roger don't know what to do hayiaaaaaa

Answer 3

Three tries at the same question, and the bot gets it wrong each time

∠ACB=x+15° , ∠BCD=x+48°, ∠DCE=13°
x+15 + x+48 + 13 = 180
2x = 105
x = 52

so ∠BCD= x + 48
= 52+48
= 100
