Answer 1

Answer:

Step-by-step explanation:

2)   <A = 180 - <D   (Consecutive angles)

     <A = 180 - 100

          = 80 degree

So, <x = 80 / 2  =  40 degree

Similarly,  

         <B = 180 - <C  (Consecutive angles)

         <B = 180 - 50

               = 130 degree

So, <y = 130 / 2  =  65 degree

Now,

      <APB = 180 - (<x + <y)      (Sum of angles in a triangle is 180 deg.)

=>   <APB  = 180 - (40 + 65)

=>   <APB = 180  - 105

=>   <APB = 75 degree
