Multiple: 5 * the result of step No. 4 = 5 * 30 = 150

Add: 8 + the result of step No. 5 = 8 + 150 = 158

Tell whether the angles are complementary or supplementary. Then find the value of x.
Genrish500 [490]

Answer:

x = 33

Step-by-step explanation:

Two angles are complementary as the sum of two angles is 90

x + 24 + x = 90        {Combine like terms}

  2x + 24 = 90      {Subtract 24 from both sides}

          2x  = 90 - 24

         2x   = 66

          x   = 66/2

         x = 33
