Answer 2

Answer:

Step-by-step explanation:

a)straight line= 180°

      therefore,  x+ 25° + x + 15°= 180°

                                      2x+40°=180°

                                              2x=180°-40°

                                                 x=140°/2

                                                 x=70°

∠AOB= x+25°= 70+25=95°

∠BOC=2x+15= 2×70+25=165°

b)∠AOB+∠BOD+∠DOC=180°

   y+150-x+x=180°

         y+150=180°

               y=180-150

                y=30°

hope it was helpful...
