Answer:

Step-by-step explanation:

Complementary angles add up to 90

6x + 29 + x + 5 = 90

6x + x + 29 + 5 = 90

           7x + 34  = 90

                   7x  = 90 - 34  {Subtract 34 from both  sides}

                   7x  = 56

                    x = 56/6   {Divide both sides by 6}

                    x = 8

∠A = 6x + 29

     = 6*8 + 29

      = 48 + 29

∠A = 77°
