Question

in the given figure find the values of angle DCE if angle BAC = 70 and angle CDE= 55​

Answer 1

Answer:

70 digree

Step-by-step explanation:

In traingle ABC

AB=AC, hence, ∠ABC=∠BCA

Given, ∠BAC=40

∠ABC+∠BCA+∠BAC=180

∠ABC=∠BCA=  

2

180−40

​

=70

therefore, ∠BCA=70  

∘

 

Now, ∠ACD+∠ACB=180

∠ACD=110

In ΔACD,

∠ACD+∠DAC+∠ADC=180

∠DAC+∠ADC=70
