Answer 1

Answer:

d = 24

Step-by-step explanation:

The external angle (98°) is equal to the sum of the opposite internal angles (2d°, (2d+2)°). This gives you an equation you can solve for d.

  98 = 2d + (2d+2)

  96 = 4d . . . . . . . . . . . . subtract 2, collect terms

  24 = d . . . . . . . . . . . . . divide by 4
