Answer 1

Answer:I am not telling the answer. But an example

Step-by-step explanation: In ∥gm opposite angles are supplementary.

Therefore,

                ∠B+∠D=180  

∘

 

            2x+25+3x−5=180  

∘

 

                    x=  

5

180−20

​  

=32

   ∠B=2x+25=(2∗32)+25=89  

∘

 

   ∠D=3x−5=(3∗32)−5=91
