Respuesta :

B-35 degrees
Why because it is a complementary angle which sums up to 90 degrees subtract 90 and 55 you get 35 degrees

Solution:

Note that:

  • 55 + x + 90 = 180

Solve the equation to find the value of x.

  • 55 + x + 90 = 180
  • => 145 + x = 180
  • => x = 180 - 145 = 35°

Option B is correct.
