hope u under stood

Step-by-step explanation:

sum of angles in linear pair is 180 degrees

Answer 2

Answer:

Step-by-step explanation:

a..    76° +x = 180°   [ linear pair axiom]

            x= 180° -76°  = 106°

b.   2x + 4 + x  = 180°    [ linear pair axiom ]

         3x     = 180-4  = 176°

          x   =  176/2   = 88°

so x = 88°

2x + 4 = 88 + 4 = 92°

c.   x-36° + x  = 180°

              2x = 180 +36  = 216°

                 x = 216/2 = 108°

so, x = 108°

 x-36 = 108 - 36 = 72°

hope it helps you very well
