Answer:

Explanation:

Exterior angle property:

Exterior angle of a triangle equals the sum of opposite interior angles

∠WBC = ∠D + ∠C

18x + 5 = 46 + 8x - 1

18x + 5 = 8x + 45

Subtract 5 from both sides

18x = 8x + 45 -5

18x = 8x + 40

Subtract 8x from both sides

18x - 8x = 40

10x = 40

Divide both sides by 10

x = 40/10

x = 4
