<h3>Answer: 24.3</h3>

============================================================

Work Shown:

Apply the tangent ratio. Make sure your calculator is in degree mode.

tan(angle) = opposite/adjacent

tan(B) = CD/BC

tan(39) = x/30

30*tan(39) = x

x = 30*tan(39)

x = 24.2935209958502

x = 24.3

Answer:

$10x - \frac{1}{x} = 3 \\ 10x = 3 + \frac{1}{x} \\ 10x = \frac{3x + 1}{x} \\ 10x \times x = 3x + 1 \\ 10 {x}^{2} = 3x + 1 \\ 10 {x}^{2} - 3x - 1 = 0 \\ 10 {x}^{2} - 5x + 2x - 1 = 0 \\ 5x(2x - 1) + 1(2x - 1) = 0 \\ (5x + 1)(2x - 1) = 0 \\ \\ 5x + 1 = 0 \\ 5x = - 1 \\ x = \frac{ - 1}{5} \\ \\ 2x - 1 = 0 \\ 2x = 1 \\ x = \frac{1}{2}$
