Answer:

∠ DBC = 41°

Explanation:

∠ DBC + ∠ DBA = 90° , substitute values

6x + 5 + 8x + 1 = 90, that is

14x + 6 = 90 ( subtract 6 from both sides )

14x = 84 ( divide both sides by 14 )

x = 6

Thus

∠ DBC = 6x + 5 = 6(6) + 5 = 36 + 5 = 41°

Answer:

8x + 1 + 6x + 5 = 90

14x + 6 = 90

14x = 84

x = 6

<DCB is 6x+5

6(6) + 5

36 + 5

41
