Answer 1

n = 8

Explanation:

Given ∠BN bisects ∠ABC:

∠NBC = ∠ABN

and

∠ABC = ∠NBC + ∠ABN

2n + 18 = 2 × (2n + 1)

• Multiply two with inside the parenthesis.

2n + 18 = 4n + 2

• Transfer like terms to the same side of the equation.

18 - 2 = 4n - 2n

• Subtract terms.

16 = 2n

• Divide both sides by 2.

8 = n
