Answer:

∠ DBC = 41°

Step-by-step 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: x = 21°

Step-by-step explanation:

37 + 4x + (3x - 4) = 180° Original Equation

37 + 4x + 3x - 4 = 180° Commutative Property of Addition

7x + 33 = 180° Combine like terms

7x = 148° Subtract 33 from both sides

x = 21° Divide both sides by 7
